temporarily sealing bodywork

[Low88]

I have been doing alot of flap discing on welds the past few nights. I have been spraying a quick coat of weld through primer on it to make sure it doesn't corrode.. Is this a decent practice? Should I be doing something else, or nothing at all? I grind/weld or do something else to the body virtually every night now.

depends on how long you're leaving it. if i'm coming back to it in the next day or two i leave it alone. if its going to be a little bit, i keep a can of self etch close by and dust that on there, then follow it up with some transtar 2 in 1. both in a rattle can, both not cheap. handy for doing little spot jobs.

I come back to it the next night as of now. The plan is to grind everything clean and epoxy seal or self etch when the temp is 70 out. I am a little iffy on heating the garage in the cold, so i might have to wait till spring to epoxy it.

Unless its possible to spray epoxy primer in 50* weather. Maybe i can over activate it?

I wouldn't paint anything in weather under 70. Rattle can self etch is your friend for sealing up metal from moisture.

:iamwithst This is what I do as well.

No don't add extra hardner/activator it will make the primer very brittle and it won't hold up. Just use a small electric radiator(space heater) to heat your garage and you will be fine. Heck I've primed/painted stuff with a propane heater in my shop/garage back when I had to do stuff out there. Got rid of the overspray real fast, with a 4 foot tall flame coming off of it!

I had a guy contact me about doing some sidework for him in his "paint booth". I showed up, it's one of those 15x15 wood buildings you buy at home depot, and it was about 4 feet off the ground. roll the car in, tape it up, and crank up the ole propane heater. I was nervous as hell!

Yeah it really isn't the safest thing to be doing, but you gotta do watcha gotta do to get by, although I will never be doing it again, I will be building a heated shop and buying a paintbooth within the next couple of years, once I find some land to put that and a house on.

[Low88]

Yeah, i just bought this house, not really wanting to blow it up. Im nervous enough about the neighbors narcing on me when I spray the jams/tubs when its finally nice. I will have a ghetto rigged positive pressure booth with filtered exits setup, so I hope its not too bad. They are only like 30' away though.

Amen - use it !!!!

[Low88]

Can I 2K or epoxy over rattlecan self etching? Or do i have to sand it all off again... It would be great to be able to epoxy over it come spring...

[99gixxer]

i would sand it off

When I'm priming something and there's small bare metal spots, I shoot some rattle can self etch on it, let it flash a couple minutes, then prime it like normal. If you let it sit for a while, I'd run some 320 over it and then prime

[KingSobieski]

Doesnt the self etching primer eat into everything below it - filler/primer? It is acid based after all.

[Beyond Static©]

You don't want to spray it heavy over anything but metal, but if a little gets on paint/bodywork, it wont hurt.

:word:

and even over bare metal you dont hammer it on. two medium coats and its done. and like kyle said, if in the booth, just dust a little on and seal over it.
