http://www.harfordcountyautobody.com One of the most important questions to ask an auto body shop is; if they use new, aftermarket or junkyard parts, as well as offering a lifetime warranty on the work they perform. This is a very important question to ask because the last thing you need is your car body rusting or your paint peeling where the work was performed. If your insurance is going to be responsible for paying for the repairs, you want to find out which kind of parts they will pay for.
