I am currently thinking about fixing the deterioration of the inside of my hard top. Its completely eroded and beginning to rust. Question I have is what did the stock hard top have inside? I can't tell if it was just paint or some sort of lining that has deteriorated over the years. I was thinking about sanding it down and putting down a few coats of primer then repainting. Unless there is a lining I can find which will be better. Any ideas on this? Thanks
