I went to autozone yesterday, and i had three spray cans I was going to buy. one was a plastic adheson, second was the color, and third was the clear coat. My instincts told me that I was right. I decided to ask the guy that worked there. He looked like he knew what he was talking about. He told me to go with Rustolium fabric and vinal paint. I first Sanded whiped everything down, and then cleaned again. I did three coats of the color. and I can see it cracking. I dont know what to do. Help!!!! i painted basicly all the silver parts and some black parts. (excuse my spelling)
