POR-15 or paint for frame

[rustbucket]

POR 15 is great stuff! It’s hard as a rock, yet doesn’t chip. Powder coat is great for garage queens, but you can’t easily repair chips and scratches. If you want to spray, get a couple of cheap guns from Harbor Freight. My brother ruined a spray gun from leaving the stuff in it too long. You do need to top coat POR 15, since it is affected by sunlight. I hear good things about Rustbullet too, and it does not need the top coat.

Is there a visual difference between using a foam brush and a regular paint brush? I'm about to do my frame.

I used rust bullet for the first time recently, I did everything they told me and even used their metal prep.
It made these small micro bubbles everywhere in the paint and I was not impressed, then the recoat window was pretty short and I really needed to take a DA sander to it all and do another coat the get rid of the bubbles and said screw it and did just 1 coat.

I never had the bubble issue with POR15.

Just going with sand blast, degrease, black epoxy and a black chassis paint from now on.
