painters!!! rubbing alcohol as prep cleaner??

I use Auto body wax+grease remover. Ask for it at a local parts store/auto paint supplier.

The only time I have used alcohol wipes is when cleaning after body filler before applying polyester primer or priming over polyester primer. Before I work on any panel I use an auto body intended wax+grease remover.

One wipe I have used for this is DeVilbiss DeWipe-Outs Pre-Saturated Prep Wipes, and they work to pick up filler/primer dust and minor contaminants.
