Our shop usually uses 3M Crystal Bay 6" DA paper for prep.
Each roll runs about $23 versus about $75 for 3M's best. I forget how many sheets on each roll though.
As far to sand the clear before flames, we use 800 Hookit 2.
I have tried the DA before buffing...hard to do the switchover...we still just do the ole' wetsanding before buffing.
As far as DA's two guys use Dynabrade and I have a Hutchins. Dynabrade seams to be an excellent brand. Nice and light. Keep in mind, Dynabrade also has three different type DA sanding aggressiveness. I believe both guys have medium.
Off to the Hockey game...go Bolts!!!
