HI Fox. You might want to try a epoxy primer and paint.
I understand POR 15 is not UV resistant and needs a top coat.
Like some things that everyone sees advertised and most folk use it may not be the best choice.(think WD-40/ armourall)
Not on my truck thank you!
After all your good work and fine results protect it with the best coating.
I understand winter has hit with a deep cold front.
stay warm. Howie
Howie, in my "travels" through many different automotive forums, I have noticed that our neighbors to the north in Canada seem to have a VERY strong following to POR style paints. You seem to be an exception to the rule. I've had good experiences with using it and also complete failure where it peeled off in sheets. Working on other's vehicles and needing to warranty the work has steered me away from using such paint that didn't in my view provide consistent, reliable results. For further education on such products, can you share your experiences with POR that have you using Epoxy instead?
