Once moisture gets any penetration behind the powdercoat it's all over with. I'll take paint any day. At least you can touch it up in spots. My Putnam hitch with the awesome powdercoat turned to shit after 2 winters...:mad2:
Try rock guard :rolleyes5:, worst crap i've ever seen in my life!.Had my 95's lower body coated with it when it got a new paint job 5 years ago.2 years later there were holes popping up all over the place,..not much left of any metal today.:mad2:
Same with the new to me 07 GMC, full of rust behind the coating, i can peel it of in sheets from the bottom up. The metal is still not bad though
That is if you can get the lid off the can.
I was gonna paint today my truck's body lower half were the rock guard coating had come loose ,I tried to open a brand new can i got a year ago,...I almost turned the can inside out,..no way in hell to got the lid to budge.:nonod:
Ended up poking a hole in the top :agreed:
