I noticed that there were several people in a previous thread that said they have used a smaller compressor succesfully to paint cars. I have a 3 hp 35 gallon that puts out about 7cfm at 40psi. Good for a portable, but a little below the recomendations for most guns and sanders. I know all of the reasons for getting a larger compressor and when I build my shop, thats the first thing I plan to get, but in the meantime I plan on painting at least one car with it, so any tips on making it work? One question i have is how to filter the air, since i cant install a hardline trap or filter. would a screw on disposable filter at the gun or sander be enough? Any tips or ideas would be appreciated.
thanks
