I have seen a lot of information posted about POR15, but I havent heard much about spraying it. Have any of you guys sprayed it on? I have access to a booth, so I was thinking about doing it that way instead of brushing it on.

Mike,

That stuff is way TOO THICK to go through a spray gun. I don't beleive you can thin it like ordinary paint either. The POR15 Blackcote that I used on my floor pans had the consistency of thin ketchup (almost anyway).

I also noticed that after I applied it, the blackcote would move into the lower areas of the floor pans while it was drying. It took about 30 Hours to dry. I can ceratinly see how POR15 claims that their coatings rustproof the metal because once dry the surface felt like it had been sealed with a plastic coating.

Maybe somebody else has some additional insight on this in regards to spraying it on. I am ceratinly no expert with a spray gun.

Mike, According to the manufacturer, you can thin the POR-15 products using their particular thinner. I, however, opted for the brush. I agree with sr71bb, the stuff really moves into the low spots and covers real well.

Mike, I sprayed my entire underside with POR15 "semi-flat". Didn't thin it, just poured it in the gun and sprayed. Went on fine. Cranked the material knob all the way open and ran around 35 - 40 psi. Unless you have a rotisserie to mount your car on, spraying the underside is the ONLY way to go.

I am going to build a rotisserie for the car. The whole car is gunna be blasted to bare metal, then sent into the booth for primer. I figured while I have it in the booth I ought to just go ahead and spray the POR. Probably save me a lot of time
Thanks guys

Absolutely, positively, no-doubt-about-it you must use a professional resperator when you spray POR-15. That stuff is brutal and it can do perrrrmmmmaannnnaannnttt damage to you. I know.

without a doubt and get that crap they sell with it to wash it off your hands, and...I'd use a mask just to paint it on. Toxic **** .

CarlC,
When you say a professional resperator what exactly do you mean? Are you talking about the ones that actually supply fresh air, or are you just talking about a canister type mask?
Thanks

What you need is a "cartridge" style respirator that has been fit tested for you. Make sure the carts are for organic paint fumes/mists. I use a North brand half-mask. IMO, fresh air supplied is not necessary.

Mike, My brother gave me a undercoating spray gun a while back. It's still in box, I'm sure this type of gun will work good. If your not in big hurry I'll go down to shop and get make & model of it for you. I havn't used it yet, but looks like it would blow thick material. Has a big tip on it. You would'nt have to thin material down. He told me he has used this type of gun before and worked good. He had body shop, but shut it down.(To many regulations)

Since everybody else lists their rides, I will too.
