My trailer arrived with two soft solar chargers attached to the roof top via a sort of caulk/goop. Two years later the trailer is leaking under the solar panels. Looking for a recommendation for a goop or caulk that is white or clear, and can withstand the sun and heat of the Western USA flying spots?

Sikaflex 295 is a UV resistant sealant/adhesive

Loctite has their own version cleverly named Marine Sealant

If you use a paintable formula like the first two you can also put a UV protective topcoat over the sealant which would extend its exposure limit.
