Hi just my 2 cents worth all depends on your paint & clearcoat if its not all
Scratched up & looks ok a good wash (2 bucket) & dry them I use mothers claybar
& lube detail spray wash again dry again then I use cg black light 2coats with a few
Hrs maybe overnite between the coats then cg v7 spray makes my 2000 zx3 look
Like almost LOL new the black light is real easy on easy off by hand......
