I have a dumb question... What would be the smallest compressor would you use? I have a 10 gal compressor like to use,but I thing it might just be too small for the job... now I thinking maybe I could do a panel at a time would this work? or would it be to labor intense? I don't think I could roll on the paint being I Have a bulging disc in my neck... I don't think I could hold the spray gun that long also... I would like to give it a try to paint my 80 dodge truck...
