Hi Juan,If you have some of the Brodak try a test piece.Spray with brodak first and let dry.Then put the DC over it to see if it lifts,bubbles or anything like that.If you have no issues it should be compatible.I use Sandblaster sandpaper by 3M and it is very resistant to the clogging you were talking about.The DC primer sands nicely and Yellow looks good over the white primer.Hope this helps.Trax
