The Stovebolt Site Forums The Shop Area Paint and Body Shop Painting my frame in the sun

Hello;
I am planning on sand blasting my frame tomorrow and if time permits would like to give it a coat of epoxy primer right after. Is there any problem with painting in direct sun? It is supposed to be about 79 degrees and full sun. I am thinking the frame would be to hot and not let the primer cure properly.

Thanks
Mark

Blow it clear/clean with a shop vac or leaf blower unless your sure your air supply is oil vapor free. You don't want that under the epoxy.
A tarp would do what you need to keep the sun off.
Wear approved air and eye protection shooting epoxy.
Go for it.

Thanks CASO, so its better in the shade then. My air is pretty good but will use the shop vac to blow it off. I have a respirator and goggles ready to go. I painted the front axel and springs already to get use to staying the epoxy. Went on really nice.

You don't want the epoxy to dry on top to fast.
It needs to off gas evenly.
You don't want to trap them (the 'gasses')

So THAT's what happened to my hood a while back! Turned iridescent and gray. Should have been black.

That was easy ups are for.🤔

Excuse my ignorance, but Huh?

Easy ups sounds like tent....no?

A sideless tent is a good discription :

I wondered as well....My frame is 17' long so i would need a long tent. :-)

Or two🤔

One other question I have is once my frame is painted and assembled back to a rolling chases, is it ok to be stored out side in one of those tent type garages or will the temperature changes have any affect IE rust? I live in Canada where we get some extreme temperature swings. I assume since I have blasted and epoxy primed before paint it should be ok.
It would be nice to store it out of the way while I work on the cab and body parts.

If you've gotten it well derusted and coated, it should be fine. Alternatively, you could lean the frame up against the shop wall inside to reduce it's floor space requirement. Be sure to secure it to the wall.

If you put 2K primer over the epoxy primer your good forever..

Don't put anything over the epoxy.
When your ready to work on it again just scuff it good with 180grit and apply filler or your 2part primer.
Nothing is going to beat epoxy for protection except better epoxy...

Edit: if it was me I'd shoot 3 coats of SPI black epoxy and be done with it. Let it sit out it won't care. It has uv inhibitors.
