I've tried por 15 on several parts, but the prep and humidity control during application is too hard to control. I think I'm going to try a product I found on the boat forums called. Boeshield-t9. Anyone have any experience with it?
I had mine sprayed with an undercoating when I bought it in 2003. The dirt and grime definitely sticks to the coating but it still protects. 12 years later some areas are still holding up strong but some areas on the body is starting to flake off.
