FYI..the damage is a bullet hole. the cop said it was a 22.<br />
<br />The major difference I see is the insurance company figured a used quarter panel &amp; the body shop figured repairing the existing quarter panel.<br />
Without seeing the damage, I can only guess, but you are probably better off having the panel repaired.  A used panel will have an increased risk of rust, may have had previous damage repaired, and if improperly installed it could compromise the factory engineered crush zones, increasing the risk of passenger injury in a rear end collision.</p>
<p>A skilled technician can make an invisible and durable repair to most any repairable dent.  (many insurance adjusters are clueless when it comes to what can be repaired &amp; what can&#8217;t.)</p>
<p>By all means, have them look it over.  I would even take it to a second shop to verify that it is something that should be repaired or replaced.</p>

			<content:encoded><![CDATA[<p>I need help.im in 9th grade and i need to do a research project that has to be pretty advanced.right now im going to do an experiment where im take nails comparing them to see which one rust fast like,one will be a regualr steel one,one will be painted,one will be galvanized and there will two nails used together as cathode protection.how can i make it better?i need answeres asap,please!!!!!!!!!!!!!!!!!!!!!!!!<br />
<br />One suggestion I would make is to use several nails of each type.  Carefully weigh them before and after the experiment, and accurately record your results. Unless you have a very long time in which to do your experiment, I would also suggest that you expedite the process by exposing the nails to a corrosive environment. This could be done by placing the nails in a big jar that has a small beaker of concentrated hydrochloric acid. Seal the jar and see what happens. It should take a lot less time that simply exposing them to air. Or you could possibly put the nails into a weak acid like a carbonated soft drink.</p>

			<content:encoded><![CDATA[<p>I want to get my earnest money back, and I want ALL OF IT !! I made an offer on a house with the intentions of living in it not rehabbing it. The offer was accepted, and we had the home inspected. There are a lot of things wrong with the house. It costs more money to repair these things than I can afford, and besides I&#8217;d rather buy something worth the money I would have to spend, rrather than put money into the house for major things. The house needs new windows, tuckpointing all around and a new roof. Here is a letter I wrote to the seller, tell me what u think. HELP !!!!</p>
<p>All these problems need to be remedied before this transaction can go any further. If the issues are not addressed we will continue on our search for a home.</p>
<p>FURNACE</p>
<p>The furnace/central air needs to be properly and completely installed and functioning. The furnace needs a shut off valve, and a plastic exhaust pipe. Debris in the &quot;clean out&quot; area at the base of the chimney should be removed as part of system service.</p>
<p>PLUMBING</p>
<p>The old steel piping is subject to corrosion on the interior of the pipe. As corrosion builds up, the inside diameter of the pipe becomes constricted, resulting in a loss of water pressure. This piping is typically replaced when the loss of pressure can no longer be tolerated.</p>
<p>ELECTRICAL</p>
<p>Extension cords should not be used as permanent wiring. This wiring should be removed through out the house.  Poor connections between newer wiring and the old-knob-and-tube wiring were observed. All connections of this type should be performed within junction boxes, fitted with cover plates.</p>
<p>The installation of a ground fault circuit interrupter (GFCI) is required in the kitchen and bathroom. GFCI offers increased protection from shock or electrocution.</p>
<p>STRUCTURE    </p>
<p>Evidence of termite damage was observed and there is risk of additional hidden damage since termites can do a substantial amount of damage. If the property hasn&#8217;t already been treated, a licensed pest control specialist should be engaged to eliminate further termite activity within the home. All damaged wood should be repaired or replaced.</p>
<p>ROOFING</p>
<p>The downspout should discharge water at least 5 feet from the house. Storm water should be encouraged to flow away from the building at the point of discharged. Install downspout at left rear section of house.    </p>
<p>Stairs leading to basement need hand rails. Drop ceiling in same area needs to be repaired.</p>
<p>The fireplace needs a damper.</p>
<p>All appliances must stay.<br />
<br />Well did you make your offer based on it passing inspection or your obtaining financing?  Those are two very common terms when putting down earnest money.</p>
<p>Did you understand what Earnest Money was?</p>
<p>The earnest money is an amount of money that the buyer puts up to show he or she is serious about purchasing the property. The money represents the buyer&#8217;s commitment to buy and acts as an unofficial option on the property. After receiving an earnest money check, the seller will usually stop showing the property, and wait to see if the buyer can get a mortgage.</p>
<p>Earnest money is important to the transaction because it shows the seller that the buyer is operating in good faith (hence the name, &quot;earnest&quot;). The bigger the deposit, the more reassuring it is to the seller, who thinks, &quot;This buyer is serious.&#8221; It also ties the buyer to the property and keeps him or her from looking for additional properties. </p>
<p>When Do I Get The Earnest Money Back? </p>
<p>If the sale goes through, the earnest money is used as part of the cash down payment and is paid to the seller. If the sale does not go through because of a reason covered by a contingency in the contract (if, for example, the buyer could not get a mortgage), the seller should sign a release of escrow and the earnest money will be refunded to the buyer. The earnest money should also be refunded to the buyer if the sale does not go through because of a problem on the seller&#8217;s side. If, however, the buyer backs out of the deal for no reason at all, or for a reason that is not covered by a contingency, return of the earnest money may go to the seller. </p>
<p>FSBO (For Sale By Owner)  Earnest Money</p>
<p>If negotiating directly with the seller without the assistance of a Realtor®, never give the earnest money directly to the seller. If you are dealing with a for-sale-by-owner seller who insists upon earnest money before a contract can be executed, write the check to their lawyer or closing attorney or your lawyer or closing attorney, and write fiduciary agent  after the lawyers name. This money will then go into a trust, or escrow, account until the negotiations are completed, the contract signed, and all contingencies met. If the deal falls apart, you&#8217;ll get it back.  But if you give the earnest money directly to the seller, you may never see it again, or you may have to go to court to get it back. </p>
<p>Good Luck to you.</p>

			<content:encoded><![CDATA[<p>I have about 10 instruments that I like to keep out of their cases. Is it ok for me to keep them out of their cases, even though I don&#8217;t usually play all of them every day? I take the mouthpieces out. They are safe from being knocked over, but I&#8217;m worried about rust and corrosion. Is there anything, such as regular cleaning and oiling, that I can do to insure that I can keep them out of their cases, making them readily accessible, without hurting them?<br />
<br />Safest place is in the case.  WHY do you want them all out?  And if you want to display them because they are ornate, or rare &#8211; then invest in glass cases.  I have over $100,000 worth of musical instruments that I use professionally &#8211; they are IN THE CASE unless being used.  And the are all insured but Clarion &#8211; the outfit that insures MOST pros instruments.</p>

MPA launch the Merus ring in Australia and New Zealand. The worlds most advanced system for stopping rust, lime scale and bio-fouling and corrosion in all water bearing systems.</p>
<p>Rust&#8230;<br />
Turns water brown and can corrode a steel pipe causing leaks and malfunctioning equipment. Sometimes blockages can occur for example rust flakes may block a Fire sprinkler head. The Result&#8230; More Maintenance &#8211; Broken machinery &#8211; Brown water &#8211; Blockages &#8211; Leaks.</p>
<p>Lime scale&#8230;<br />
is an insulator and will reduce heat transfer. Lime is found in almost all water in its dissolved form. Lime precipitates and deposits in pipes, machines and on other surfaces as a stone hard substance. The Result&#8230; Blocked Pipes &#8211; System failure Higher energy costs &#8211; more downtime.</p>
<p>Bio-Fouling&#8230;<br />
The growth of algae other bio film organisms can occur in some water systems. Sometimes this results in deadly bacteria such as Legionella. The Result&#8230; Legionella disease &#8211; - More maintenance &#8211; More downtime</p>
<p>Merus&#8230;<br />
Reduce energy costs, no more blockages from scale, bio fouling, algae treatment, No more brown water, Much less or no maintenance, Much less or no downtime.</p>

			<content:encoded><![CDATA[<p>ok, in chemistry class we have a new teacher for the next few weeks and she teaches really differently. i&#8217;ve been flat chat doing homework for all my other subjects and i really dont have time to try and re-learn what she is trying to teach us. could you please help me with several questions i need answered ASAP, i understand corrosion but not so much the differences in materials etc. so for the questions could you also make reference to WHY, ie their positions on the electrochemical series. thank you so much.<br />
-why is it undesirable to coat screws with tin as a mean of protection?<br />
-cadmium is often used to coat screws, why?<br />
- a yacht made of copper alloy sheets fastened with steel screws begins to leak after only a few weeks in the water, why?<br />
-given a choice of an off road vehicle having either a chrome plated steel bumper or a galvanised steel bumper, explain which one you would choose and why?<br />
-explain why it is not necessary to apply a protective coating fo aluminium sheeting used for roofing?<br />
-aluminium is suitable for manufacturing small dinghies but not for large ships, why?<br />
-steel anchors that have been left on the sea bed for decades show little or no evidence of corrosion, why?</p>
<p>sorry its so much, but im snowed under with work just now and i&#8217;ll get around to learning it as soon as i can. stupid new teacher. =/</p>
<p>thanks babes xx<br />
<br />Hi . Several answers for you:</p>
<p>We never join two different metals because they create a galvanic cell in the presence of water, so the net result is one of the metals is corroded.</p>
<p>Aluminum is covered with a thin layer or aluminum oxide that doesn&#8217;t penetrate within the material more than a few mm. So, no paint required. Paint costs money and adds to the weight of the project.</p>
<p>Aluminum is used for larger ships, especially military ships &#8211;  advantage &#8211; non-magnetic (not affected by magnetic mines). In general, aluminum is difficult to weld, so maybe, the answer to your question, smaller boats use aluminum structure joined together by rivets (quite labor intensive compared to welding).<br />
Hope this helps.</p>
