I was doing a solar panel project last weekend and at 5:00pm on Saturday realized I didn’t have usable sealant aboard (my 4200 had cured in the tube). At the time and place, my best bet was a nearby Home Depot, and took off in search of....
The HD had 5200 in large tubes, but I’m not a fan of 5200 for various reasons. Right next to that they had PL Marine Adhesive Sealant. http://www.loctiteproducts.com/en/p...loctite_pl_marinefastcureadhesivesealant.html
“Loctite PL Marine Fast Cure Adhesive Sealant is a fast setting, moisture cure polyether adhesive sealant which delivers strong bonds while forming a watertight, flexible seal above or below the waterline once cured. Free of solvents, phthalates and isocyanates, it will not shrink when cured, discolor from UV exposure, or bubble on damp surfaces. Once cured, it withstands both saltwater and freshwater environments.
(Also, it is about 30% less expensive than the 3M alternatives).
