cleaning caulk from gelcoat (turpentine, naptha or acetone?)

I'm rebedding some hatches and was wondering after I scrape off as much of the old caulk as I can from the opening what I should use to give it a final rub down before setting the new caulk and to clean any drips of the new caulk (using life caulk). I've got already turpentine, naptha, and acetone.

I have been sanding to get a virgin surface and then wiping with acetone. Seems to be yielding good results.

George is right. Sometimes, the best way is to simply use a very high grit sandpaper, which isn't all that different than using softscrub or a fiberglass cleaner designed to cut the chalk.

I sanded all of ours with 220 grit when rebedding. I use the sandpaper on any of the stuff that wouldn't come off using other methods (such as Collinite's Fiberglass Boat Cleaner).

Acetone

is a dry solvent. It will NOT leave a residue behind allowing the new sealer to adhere. MEK works better on hot or windy days........................_/)
