anybody using por 15 as an undercoating. i am deciding what I am gonna paint on the bottom of my body

i personally haven't, but i have a lot of friends who have. they love it, they say it doesn't chip away or let the rust come back.

I sandblasted the entire underbody,(frame off),done the complete POR thing,spraying on 2 coats,and then used spray undercoating on top of that for the textured look. Not alot of fun sandblasting it, but it came out great.

thanks I will use the por 15 then
