Just throw my satin spraying experiences in the mix...
I used 4:1 as a Paint:Thinners ratio, and 40psi. I opened the garage door, and that was it as far as ventilation goes. Using mineral spirits meant it wasn't too smelly - so I actually got NO complaints from my wife!! Try that with a Urethane...
And the same comments apply re runs - if you get any, just quickly wipe them (and the roller idea sounds better than my finger) and let the coat self level. You can rub them out when the coat's dry anyway...

It depends on the size of your car and the size of your garage, but I'd think that a 20 foot hose might not be long enough, and you don't want to drag the hose across a freshly painted panel...

One thing I did find when I was using a touch up gun for door jambs etc was that the paint would dry at the tip of the gun, and therefore the paint supply disappeared. The cure was to periodically wipe the tip. That only happened on the touch-up gun however - probably because the nozzle was SO much smaller than the 1.2 I used with the real gun.



1.2mm tip for the car? Cool- Thanks for the info. My garage is very tight- I might have to spray one side, front and back. Wait for it to dry then move the car and spray the other. I dont think i will but would this affect the job?

What filters/water traps did u use? I had to replace the one I had on the compressor as it was an oiler/filter... I mainly used it for air tools.

Also I'm getting a 50 foot hose today aswell as a p/s reg- thanks!



My HVLP gun had a 1.5mm tip, that seemed good for anything, single stage acrylic enamel, BC/CC, and tremclad, just make sure you have no water in your system, and i allways like to clamitize my compressor just prior to paint, putting the tank pressure to 5/10psi and putting an elastic on the paint gun trigger which is empty and let it run for 20 mins or so, then clean the gun, and blow out the hose really well, i find that it reduces the amount of water that condenses in the compressor, i also drain all the water out of the tank after running it dry like that. Also i ususally keep the compressor out of the garage, otherwise the intake will get really plugged. I paint typically with 30-45psi on the HVLP gun. You could also do a dry practice run, with no paint in the gun and plan out your spray technique, basically going thru the motions without painting the car just planning your attack of all the pannels, you may find depending on the car your painting, that you've left an area for too long before getting back to it, and you can alter your order of painting. ALso, one big issue you'll have painting in your garage, is fall-out, the paint in the air that likes to settle on your hood and roof, i try to do the sides first, then avoid the roof/trunk/hood, and let the air clear for a bit, and tack the roof/trunk/hood with a tack cloth and then paint the flat surfaces, otherwise you may end up with some fallout on your pannels, espically with single stage paints. With tremclad/rustoleum i did'nt have that problem as much almost not at all. I find the tremclad/rustoleum does'nt linger in the air as long, and smells about 90% less than single stage auto paints.
