My truck is an 02 from Texas with no rust and hasent seen a salty wet winter here in Vermont. I was wondering if I could get away with rustoleum rubberized undercoating from a rattle can, or would it be worth it to put on some por-15? My concern about the por-15 is not adhering well on factory paint unless i scuff it up pretty well? I plan on doing axles, frame and undercarriage. Any advice would be great thanks

Any ideas for best protection??

 

Im not even using underliner im using herculiner or rhino liner best way is probably to paint it on to rather than spray it less messy as well. From my experience underliners dont last very long.

 

Por-15 works well. you will have to scuff up the paint to get a good stick but its worth it because its a good coating. dont get it on your skin though, it doesnt come off until the skin does
