I had to post on this thread. My father is like Mr Chemical when it comes to new paints, solutions, waxes, etc.
We first used POR 15 back in 1987 on a 63 Impala SS that we restored. We later used it on a 68 Corvair in 1989 and a 65 Corvair in 1991. I recently saw the 68 Corvair after not seeing it for 10 years and the POR 15 really does work. There is not one spot that I could see on the undercarriage that peeled, chipped or cracked. The 65 Corvair was sold last year and again, the samething......in almost 10 years, the stuff really held up nicely. I plan on doing the undercarriage of my GN soon and also my present Corvair project.
