Works perfectly. Used it seal an outdoor solar panel for a motion light and a vinyl seat cover for my jetski. It drys clear and remains flexible.

Handy sealant

Dries quickly with good seal and tack.

Put a van camper top on my van

This is one of the best tubed I've used. Keeps the water out. Keeps the moisture out. Doesn't expand too much. Goes with the hot weather and the cold weather. Very easy to work with. Smells at first. But when you get done your job looks awesome. Doesn't peel the way like the other ones do. I ended up buying 8 more. To put my camper van top on. And it's still going strong. I recommend this to anyone. Easy cleanup.

Can always count on 3m marine sealants

Perfect for boats and easy to work with. Would purchase again.

This stuff is great - we use it for everything boating related and also used it to seal our new shower doors !

It does act as a glue to keep my solar panel cable blue to the bottom of the panel. I kept one of my connections under the panel instead of running it through the mounting shaft so that if it ever came loose I could simply plug it back in. I used this to glue this to the bottom of the panel and it works. I used this to plug up my holes I drilled underneath my pontoon through the plywood floor which also seems to took well.
