Will my air compressor run an air sander and a paint sprayer?

I'll be painting motorcycles (tanks,fenders)using a HVLP paint gun. Also running a National Detroit air sander...the paint gun requires 15cfm@ 29psi, Will a 60 gallon "single stage" air compressor rated at 13.3 cfm @ 90 psi run it or do I need an 80 gallon "2 stage"? I know the difference in 1 and 2 stage pumps, I don't want to run out of air and screw up a paint job...or have to wait on air to build up. Thanks

Thanks for your question.

Are you sure your paint gun requires 15 cfm? That sounds really high. Your average paint sprayer should not need more than 6 cfm and the air compressor you have should have no problem. A single stage 60 gallon air compressor will have no problem with your air sander either. Good luck with the paint job!
