Talked to a guy in Home Depot and I asked him if this tub repair stuff works...He said he didn't know, he restores cars. He has a Porsche and Corvette. I asked him if he does body work ( the famous parking stops ), I have an SLK and have some damage (answer was no). He said his wife has a 2004 SLK...Talked a bit and gave him a business card and told him to check us out. Also mentioned the BBQ coming up. With all the cards I have given out you would think someone would respond !!
