I painted the frame and floor on my K5 about 10 years ago, everthing was sand blasted and I used POR15 (Paint Over Rust) as a paint and primer! I ran out of the POR15, so I used epoxy primer and enamel on my gas tank and the gas tank guard!! Well after 1 year the POR15 started to fade and flake off ( I was fired up), the gas tank and guard still look nice (after 10 years) w/o any problems!! Since I`m a painter and I have many years of experience, I found that epoxy primer and a couple coats of enamel will last much longer and it is cheaper, about half price!! So don`t make the same mistake I did!! POR15 is a very expensive and very toxic paint!!! I was lucky I ddin`t use it on a customers vehicle!! I`ve talked to others in my profession and they have had the same problems!!! Does anyone have any horror stories? Any good stories?
