Temperature Question

First, let me say hello and thanks for all the great info here, I've learned 90% of what I know about painting (which still lacks alot) on this board.

I took the leap and got set up with a makeshift spraybooth in my shop. I did a solid test fender the other night. My problem is that my shop is not heated, and was probably about 35 degrees when I shot the paint.
It came out good with the exception of very fine lines starting at the top center of the fender (the apex) and going out in all directions. It was cool looking, but not what I need. I'm thinking it was just WAY too cold to spray the stuff.
How can I get some heat going without blowing myself up in the process? Does anybody have a good (cheap) home setup they like?
BTW, I'm using PPG Omni MBC.

Thanks alot,

Chop

Ooh,way too cold,I'm surprized it didn't slide off on the floor.If you have an enclosed booth made you can get some LPgas heaters like space heaters and direct the heat toward the intake as the fan is running.If you can get to at least 60 you can start painting but 65 is pretty much the minimum.Even at 65 the fast reducers are slow drying.

You'd be surprised how well it turned out, considering it almost froze before it dried...

I'll have to figure out a way to channel some heat in there. I may have to do a little extra on my booth before I can safely heat it up.

I don't want to sound like a complete idiot here, but how flammable are the fumes, anyway?

Chopper, I shoot in my garage - 12 x 23, and use a kerosene heater. In my ceiling I have a fresh air source from the attic. At the other end I use a squirrel cage fan that I mount in my window. With the heater placed under the fresh air vent, next to my garage door. I can get the temp up to 90 degrees without my fan on. I've shot clear when the outside temp has been 20 degrees. BUT - I work it a little different, I'll mix some extra catylst in and turn my fan on and off when shooting - For instance - I'll let the room heat up - Turn on the fan for say five min. to clear the room of dust , turn off the fan and build up temp. then turn it back on when I'm shooting and wait for the room to clear the overspray, then turn it back off. The coldest it's ever been was about 40 degrees, of course this isn't the optimum temp. but it will work. It takes longer to flash and cure before you can sand and buff, but I've had pretty good success. Peace! Bones!~

I have a woodburner outside of my spraybooth in my garage.(I know, an accident waiting to happen.) There are fresh air vents on one of my walls in the booth which suck in the heat as the exhaust gets the bad stuff out.
I want to insulate everything so it holds it in better. I have been able to spray at about 65 to 70 degrees in there even in the crap weather we've been having. I think the several inches of snow on the roof and the drifts against the walls are somewhat of an insulation.

To answer the Q the fumes are HIGHLY flamable.Common sense is all you need.Hell,I've had a smoke in between coats if the wind was blowing at the door so I didn't chance any dirt blowing in.Pay attention to the amount of overspray and/or the amount of fumes you can smell and the amount of ventilation.If you have all the doors shut and oyu can smell the fumes it volatile,if the doors are open it's still so but the ventilation lessens it as long as there's a breaze to keep a flushing action going.

Twisted,free insulation eh?I'll pass

Just be careful buddy.If it works it works but don't get relaxed and nonchalant(sp) about it so you wake up in the neighbor's tree.
