Some questions from a reader:
1) I have heard that it is tough to get paint to stick to POR 15. What primer did you use and did you have problems getting it to adhere to the POR 15?
2) How did you sand blast the area? I need to sand blast an entire tub, fenders and hood. I had the frame sandblasted but the medium used left lots of pits and a rough surface. Not sure I want to use the same thing for the tub, etc.
Answers:
1. I've never had any problem getting paint to stick to POR, I've just primed right over it. If you're looking for something better, try this
TIE COAT PRIMER-POR-15 Inc.
2. I've only sandblasted small things, never an entire body, and I've actually heard that sand can be rough on the metal. You can blast with alot of different media, I know that baking soda and walnut shells are both gentler and are pretty popular - you might be better off blasting with something else
