Charlie,

Hope all goes well for you! Sounds like you have solar.

One of the best adhesives I have used is the canned foam called “Great Stuff” sold at Home Depot and other home stores. I used it to glue rubber padding to the side of the hull in the anchor locker in 02 or so. Still working great. It sprays in through a tube, allows a few min to work with and cures hard and is foam.

CAUTION, don't get it on you or anything else you don't want it on! It's very hard to get off. As long as you are the home store getting it, get some thinner or “Goof Off” just in case. I always plan ahead and never think I will need it, and always DO need it....

Just an idea.
