Yep, the residue is terrible with Celotex, not so much with aluminum as with carbon. Wood arrows sealed with poly or gasket lacquer is the WORST. What I've found to work better than anything to keep the residue from sticking to arrows so bad is to wax the first 10" or so of the arrow with a good silicone based auto wax. Works on all kinds of arrows and generally lasts through a couple hours of practicing on the butts.

Our club went to the Morrell bags about 5 years ago and we've been happy as clams with them. But if we ever set up another 14 target field range, I'd like to find something better - and cheaper - than Celotex to put in the target frames.

Whatever happened to the days of cheap excelsior... [:'(]
