I did not have good results with Life Caulk around the rubrail. I was deciding between silicone and the Life Caulk and decided to try the Life Caulk. I cleaned the whole perimeter, then wiped the rubrail and fiberglass down with fiberglass solvent wash, and masked both sides of the joint. The caulk is all coming out in long strings, which is frustrating considering the amount of time the prep took.

I've used it several times over the years and never experienced anything like that. How Did You clean The mess, It Don't Come Off Easy.

It is coming out because there was silicone there before. That's not Life Caulks fault but the boat builder for using silicone. The issue with silicon is caulk will not adhere to the substrate where there was siliconex it leaves behind a residue.
Silicone residue is PIA to remove, even when it looks clean it is not. Painters and boat restoration places hate it.
My paint shop charged me a premium to remove my rub rail caulk because of the time/effort it takes to get it all cleaned off. It also causes fish eyes in paint hence another reason why painters hate it. They replaced it with 3M 4000UV.
Not sure why boat builders use silicone anymore esp with all of the other non silicone quality products available

It's a toss up I guess. I like both, just so long as you dont use silicone. Some say 4000 is easier to work with. You are going to have spend A LOT of time physically and chemically removing the silicone or it will be all for not.

Appreciate the info, it sounds like a good winter project.

I had the rubrail replaced as part of some fiberglass repair. I spent a lot of time using an acetone wash to clean the joint before using Lifecaulk. I would think that would get everything out of the fiberglass pores. I understand the problem with silicone and paint, and we all hate it if a pore grade is used and it mildews, but I can't recommend the Lifecaulk based on my experience. If it is silicone's fault, everyone else will have the same problem if that is what Sailfish used originally.
