Also, if not, use the largest (longest) sanding blocks possible (that the panel will allow) to block out your filler coats in a cross-sand pattern to insure the straightest panel.

As to compressors; my opinion has always been the bigger the better. However, years-and-years ago I started out with a 30 some-odd gallon air-maker and it would run a DA; but only for a few minutes. Yes, it will work but it will be an exercise in patience!
Keep in mind too, for a HVLP gun to function properly most need 12-16 FM.

Just my .02

3m makes a nice powdered guide coat too, i like it alot.

and on a spray gun note, i started running RP guns a few years back in place of the HVLP and love them the sata is even available with a pressure gauge in the handle so you can monitor and adjust pressure to compensate for compressor pressure fluctuation( as compressor charges up and drains down it affects pressure at the gun which changes how metallics lay down) The RP stands for reduced pressure
