Re: Paint (74L82AirRoadster)
Tony-
As a tree-hugger, I will confess that I have done some painting outside in my parking lot, mostly the primer coats. :rolleyes: Please don't tell my friends!
I found one place that actively rents their booth. They charge $45 for the first three hours and $10/hr thereafter. I used them a couple times, but they're far and less convenient for me. So I started knocking on doors of area body shops and found one who would let me rent their spray booth under the table for $80 for seven hours on Saturdays.
This is the first car I've painted in about 20 years and I've already had four spray booth days because of flaws (who, me?) and the shear number of parts when these cars are fully disassembled! I still need one more day! :eek:
Like you, I started wearing my respirator with spray cans, too. Once you've bought it, why not? I can't believe that when I was in college, I painted a few cars in lacquer with only a paper mask!
And to be clear, what dissipates in catalyzed paints are the poisons (not VOCs) that make it so much more dangerous than traditional paints. At least, that's my understanding. The VOCs themselves don't dissipate, it's just that there's less of them in non-lacquers.

Re: Paint (58Mike)
Guys, while we are talking about respirators, it is important that you understand the difference in the types of respirators and their use. For lacquer a mask type respirator with the apropriate type filter cartridge is sufficient, but for most catalyzed paints a supplied air respirator which recieves it's air from outside the work area, is an absolute necessity! Obviously the supplied air respirator is the best to use on any paint, but it's use is not optional on catalyzed urethanes. A good supplied air respirator can be bought for less than $500 including the air source. If you are lucky enough to have your compressor at a remote location from your work area like I do, then you can just buy the mask and a belt clip regulator to feed the mask from your compressed air source at a much lower cost.

Re: Paint (John McGraw)
VOC stands for volatile organic compound(s). I'm not a tree hugger- such fanatical positions don't attract me- but I like to keep current and read a great deal.
John McG- does your belt regulator supply air in sufficient volume at low pressure or does it pressurize the mask??

Re: Paint (Mac)
Mac, Mine is a 3M mask and the regulator keeps the mask at a slight positive pressure and bleeding out through the relief in the mask. It is not a demand type regulator like a SCBA. It was a fairly inexpensive setup, and if memory serves me right I only spent a little over $100 for it, however that was about 9 or 10 years ago! I was advised to stay away from demand type masks as they were more expensive and required negative pressure to make them flow and with the negative pressure the possibility of drawing in fumes was a possibility. While drawing in a very slight ammount of fumes from the spray area would probably not be a problem like it would be in extermely hazadous enviroments, I decided to stay with the simple setup. The only real reason I can see for demand type systems would be to conserve air and if you are not using tank air, then the point is moot.

Re: Paint (John McGraw)
Makes sense to me! The first time I saw a supplied air system, I thought it was overkill but then I did some reading about the epoxied primer* which I was getting ready to spray and decided the mask wasn't such a bad idea. I also got a paper 'bunny suit' to minimize skin contact.
*the formulation I sprayed included lead (LP90, if memory serves) and has since been changed to eliminate the lead because of health concerns.
