Looking very "straight", Marty 

Just comparing notes - in between coats, I usually use 600 grit wet/Dry, and I usually dampen the sandpaper and leave the cab out in the sun to dry. It gives me a REALLY smooth cabinet for the second and third undercoat. After the last undercoat - I leave the cab for a week.

but - I usually "hand" sand the cab just to get a "feel" for the job.

I'm interested in your methods.

What grit are you using on your sander ?

what type of primer are you using ?

The results are outstanding !
