Frame Restoration
I have a 1991 f250 frame I was planning on sandblasting and painting. I want to use POR-15 is there anything I should watch out for or do before I paint it? The frame is going to be for my 93 f150. I've heard you should paint over the POR what paint did you use?

Well, from what I've been told, you don't need to sand (soda) blast a rusted frame with POR15. It is designed to be sprayed right over the rust and whatever chemical is in it supposedly stops further oxidization. POR 15 is designed to be the coating, the paint, that is exposed to the air, supposedly it actually gets stronger if you DO NOT paint over it.

If you're sandblasting, I don't think you need to do any other prep work. And sandblasting is the best way to go.
According to the website for POR-15 you should topcoat if it will be exposed to sunlight, because the UV rays will break down the POR.
When I get mine done I will be using . I've seen some really good results with other people using it.

that's what i was going to say as well.if your doing the best prep possible (sand blasting) then don't bother using a paint designed to paint over rust.use a quality primer/paint of your choice.
i like that valspar enamel as well.im having my commercial wood chipper fixed up/welded/other fixes and finally going to have it sand blasted.im thinking of bed liner on the thing to hide all it's imperfections.

I have done this on quite a few trucks
1. strip chais as much as possible
2. sandblast to white metal
3. spray POR15 as a primer
4. while wet topcoat with chassis black

does anyone know what ford uses on their new trucks for frame coating, and if they sell it?
that stuff seems to be the best frame coating ive ever seen, of course time will be the only way to tell. stuff is rock hard.

Typically Cosmilne and a power washer takes it off fairly easily
