Re: For sandblasted frame: POR15 or Chassis Black or?
Ive also had good luck with POR on my frame and underside.
It needs to be applied over tooth,not smooth.
Its very durable,and held up five years and counting on the street.I used the gray.
I didnt topcoat it because if the underside gets any sun,Ive got bigger problems,lol.
I'd have a hard time putting it over something freshly prepared though.
FWIW,POR is unbeatable in between fenders and braces for rustproofing,and all those other crevices a spraygun will not reach,or a sandblaster.
