Freezing temps,filler and primer
 

I have accidently left my body fillers,epoxy primer and 2k primer and assorted spray paints in the garage in temps below freezing. So,do i toss them out and buy new or can i still use them?
I tried them and they all seem to be ok. Is there anyway to tell if they did freeze?

not an issue.

J.D. is correct.

Great. I didn't want to have re-buy all this stuff. Thanks.

just dont try and apply them while its freezing.
Funny I just thought of a story an old timer told me
when we were huddled up next to a wood stove in his shop.
He had a car to get done and it was cold,shop never did come up to ideal temp with the wood stove.

He put the paint on top of the wood stove and kept stirring it,no reducer,
Paint got thin enough to spray and he shot it with no reducer.
He said it was the slickest black enamel job he had ever seen.
Myself Im not a fan of enamel,except on ag equipment.

Cammer-6: it is a common practice in industrial spray painting operations to install in-line heaters to control/reduce the viscosity of paint. Added benefits are lower VOC emissions (less solvent needed as heat is used to "thin" the paint instead) and better flow-out, as you witnessed. I would caution anyone trying this at home with any 2-component product (epoxy or urethane) as heat will shorten the pot life, sometimes dramatically. When 2-component paints are heated, the individual components are usually heated seperately, and then automatically mixed thru a static mixer right before the spray gun.

I have a neighbor who did nothing but build totals for a living. Back in the day when DuPont "Dulux" was the best there was used to heat his paint on a hotplate, pour it in the gun and do an overall. He turned out some really nice paint jobs, too. I was always afraid of fire, but it worked for him!!

JWW

When I first started working as a painter one of the old timmers at the shop told me about heating enamal and getting a "slick" paint job. He called it hot plateing, as you might have guessed they heated the paint with a hot plate.

ON a reverse side of this I have put catalized paint in the frig tightly sealed and its been ok for up to a week
I wouldnt do this on anything that was a show piece tho

I once sprayed Centari enamel by thinning it with lacquer thinner instead of reducer just to see what would happen. It went on very smooth,and dried quick like lacquer and had a great gloss.
I miss the old days when paints were much more forgiving and easier to use.Just thin to your liking and spray. About the only thing to worry about was to not spray lacquer over enamel.

I have heard if you store it at 50* or lower it can last a really long time that way. Never tried it myself.

Ive already proven that
I also experimented with catalyzing using half the catalyst and storing in frig,mixing the other half when ready to spray.It lasted longer than a week but started to wrinkle when sprayed at about 2 wks old.It would also kick alot quicker.
