Pelican racer Posted December 9, 2021 Report Share Posted December 9, 2021 Looking for anyone that has used boat life life seal for deck joints. I have two joints on the gunnel that were previously sealed with sikflex. It was very gummy and held the dirt. I removed it and it looks like I’m down to choosing 1 of 3 products. Boat Life life seal 3M 4200 or 3M 4000 Trying to find something that lasts and doesn’t mildew. My 2005 PF had white caulk/sealant that was never a problem and never had to remove it just clean it when I cleaned the boat. Thanks.

I have not used Boat Life LifeSeal on deck joints, but have used it above and below the waterline everywhere else. It would be my first choice. Great adhesion, no mildew, and strong bond - but still removable without damage to gelcoat and fiberglass. Second choice would be 3M 4000 over 3M 4200 because of UV resistance. I will never allow 3M 5200 to be used on one of my boats again. 1 Quote Link to comment Share on other sites More sharing options...
Headhunter Posted December 11, 2021 Report Share Posted December 11, 2021 Just a quick counter point. I used GE silicone white on the joints of my 22TE. Five years later it still looked new and no mildew. It is a little harder to work with but it worked well for me. Somewhere on here is a post I put up if you want to go digging for it.. good luck with your project. Quote Link to comment Share on other sites More sharing options...
SCFD rtrd. Posted December 19, 2021 Report Share Posted December 19, 2021 Yep, I remember Headhunter's post. It was a complete step by step instruction to remove and re-install caulking. It will be well worth your time to dig around till you find it. Quote Link to comment Share on other sites More sharing options...
