I am trying to decide if I want to paint my car myself like you did. I know I can do it, just don't know if I want the hassle. What kind of paint did you use, and gun? The garage where you painted it, is it attached to your house? If so, how bad were the fumes in the house? In the garage?
I didn't see your post until now - sorry about that!
The materials I used were:
Southern Polyurethanes Gray Epoxy primer (reduced and used as a sealer) 1 coat
PPG DBC 9700 black - with DX57 activator - 3 coats
Southern Polyurethanes Universal Clear - Extra slow activator - 4 coats
Gun was an Eastwood Concours, using whichever tip was recommended by the tech sheet for the material I was shooting.
My compressor is an Ingersoll Rand SS5L5 --- 220v/60 gallon/ 5hp - rated at 18.1 cfm @ 90 psi
My garage is attached to the house. I built some fan contraptions using 4 el-cheapo box fans in wooden frames with a/c filters. 3 of them blowing "out", 1 blowing "in". That helped keep the fumes and stuff out of the house.
In the garage, it got pretty bad. I was using a good respirator and full body tyvek coverall paint suit, head sock, etc. to protect myself. I didn't use an "air supplied" respirator as a personal choice. I researched the topic a lot and from what I read, the problem with iso's is that they're odorless. A regular respirator like the one I used will protect you for a period of time, but since you can't smell them you have no reliable way to know when it's time to change the cartridges - hence the recommendation for an air supplied respirator. After my research I decided to just buy several sets of cartridges and to change them VERY frequently as I worked. Note again though that's a choice I made for me - the safest option is still to use a respirator that supplies a known good source of good "external" breathable air.
The clear was the worst in terms of creating a mist in the room and making it hard to see my work clearly at times. Larger fans that moved more air would have helped that I think. I had decent lighthing but could have used even more. I'll attach some photos.
I shot the first coat of sealer about noon on Saturday, worked all through the night and shot the last coat of clear about 9am the next morning. The good folks at SPI (Southern Polyurethanes) advised me that black is the slowest color to dry/flash so it would be a good idea for me to make sure to give it plenty of time between coats - which I did - working towards the long side of the recommended times instead of the short times, so that's probably why it took me so many hours to get all the material on it.
I got what would be considered a "lot" of trash/dust in the clear. Now that I've got the car wet sanded and buffed, I'm happy with the result. If you choose to go this route be aware you're letting yourself in for a significant amount of work. It took me not quite 24 hours to apply all the coatings once the car was masked and ready. The wet sanding and buffing afterwards took me abouth a month - and I used an air sander for "most" of it - and it's not completely finished yet. I still have some areas that need more buffing, some other areas close to edges that I need to sand and buff by hand, and some spots where I can see sanding 'pigtails' that I need to work out. Once I get the car out into the sunlight I'm sure I'll find more spots that need some additional attention --- but for the most part it's "done".
(EDIT: Now that I've read the other posts - duh... Yes, if you can find a booth to rent/use by all means do it. It will save you a lot of work dealing with trash in the paint later, you'll be able to see better, etc. My contraption did a good job of keeping the fumes out of the house, but you could still notice them if you tried - and I've got a terrific understanding and supportive wife
She wants this thing done too.)
(Another edit: So why do it? For me it was two reasons mostly. One was cost. Even with the additional prep and equipment my expense was nowhere near what it would have cost me for even a medium "show quality" job. I talked to a few restoration shops in the area and the cheapest quote I got, even with me presenting the car to them 'ready to shoot' was over $10,000. The other reason was related to that. I just didn't think that anyone else would take the time and care to do "their best" on it, regardless of how much I paid them.)
