I used 3M 4200 sealant when I resealed the bow pulpit and mast step. It is flexible and made for "removable parts". The 4200 is a fast cure and dries in 1 to 2 hrs and fully cures in 24 hrs. I think it is better than the silicone mixes for marine applications. I have used Oven cleaner to remove painted on boat names with no ill effect on the gel coat. I left on on for 5 minutes and application. Unfortunately I wish it had more effects on the old paint as it still took a lot of elbow grease. For stains I would try a bleaching agent but try it in a safe area first. Soft scrub does a decent job on the non-skid areas.

I've used silicon for caulking various ports and hatches. I've never used it, but isn't there a 3M 5xxx goop that is removable (as opposed to 5200, which isn't, very)? The manufacturer of the bronze ports that I fitted to Dolphin (New Found Metals) recommended 3M strip caulk, which is (surprise!) strips of caulking intended for fitting auto windshields -- it seemed to work.
For that port, though, I think I'd use silicon. Giles Morris

I just made the cut. I now have a hole in the cockpit face of my transom, awaiting a new 8" Beckson inspection port. Should I use silicon or caulk to mount this type of access opening?
Early posts regarding how to deal with deck stains mentioned oven-cleaner: How long should one wait after applying the oven-cleaner before removing it? If left too long, will it harm the gel-coat?
