Rust Bullet or POR 15???

[michael084]

I will also put in my vote for por15, I have used both and the rustbullet has started to bleed thru rust a month later , I put it on my rollcage, sanded the new steel and degreased with dupont 3939, very disappointed. glad I used the por15 on my differentials. Por will stay liquid for over a year if kept in the fridge by the way.

Mark, that really sucks. what did you do for prep on those floors? wonder how it would hold up if sand blasting first to good metal?

Ed, I wire wheeled the hell out of it with my 4 1/2" hand grinder. I removed ALL loose rust and then some. I applied the rustbullet on top of this. I'm sure I'd have better results if I sandblasted it, but the instructions don't call for sandblasting AND if you sandblast it to bare metal a soul could just prime and paint and have good results.

will using a wire wheel on my frame to rough it up and then using degreaser be good enough for prep? or should i do more? im excited, por15 should be here thursday and my 3 1/2 susp. system will be here friday. sounds like a fun weekend.

I wire wheeled the frame on my '77 Project Infinity and then used the Marine clean, then the "metal Ready", and then the POR15 and have excellent results. It did take a long time to do a good job. I do recommend sandblasting it if you can. ;D

Even though we had our frame sandblasted, the front end area under where the engine is located still looked a bit grimy or greasy. so we went ahead and used the marine clean just to make sure.
The POR-15 FAQ area indicated that any oil even from fingers could affect the paint from adhering perfectly, so we went ahead and did a brush on/soak and rinse off before proceeding..
If anything is worth doing well, it's worth doing it by the numbers..

Hey have you guys used POR engine paint?

i guess it would be best if i ordered the marine clean and metal ready to do it right the first time.
