    i'd like to hear about some as well. I've been using various hardware store silicone for a few years trying to find one that will seal.. I end up resealing it at least every year. everything up top holds tight but the lower stuff that gets oil/gas on it.. just eats away and starts to leak.

    Default 100%

    Use 100% silicone from home depot or lowes, it will be fine.

    I bought a tube of 3M marine grade stuff at home depot...its in the glue/fiberglass/bondo section. Sticky as hell, 7 day cure, gets all over the place. I know its good stuff because I somehow got some on my belly week and a half ago and it's still there...can't seem to find anything to dissolve it.

    I think most silicone products are gasoline soluble. Someone in the past used silicone instead of a gasket on the fuel sending unit on one of my gas tanks and I'm still fighting it.

    Locktite brand silicone works great. Bonds to everything and is super clear.

    What about using a urethane caulk? Or is that not recommended?

    urethane will not work either, they do not do well in the sun and degrade 5X faster than a silicon, you can try some construction selant companies in your are and look for a dow 795 or pecora 895 they are both structual silicons and have the highest bond strength outta all the rest, i am a caulking contractor, and would try these first.

    I use 100% Aviation grade silicone. Works like a charm and it comes in black.

    X2 Boatlife comes in black , white or clear. Its below water line sealant. I have it in stock. I used to use the 3M marine bead compound years ago, it works great but is a bear to take back off. Jim
