I am in the process of gathering supplies to remove and replace stripped screws on awning arms. I want to seal the existing screw holes with an adhesive sealant before inserting next size up screws. There are numerous products out there and one that is recommended is Lexel. But after reading about compatibility it would not work for this application as it would dissolve certain foams like polystyrene. Our units are fiberglass gel coat sandwiched between rigid foam and luan. I have no idea what the rigid foam type is. But will not be using this product for filling into the holes.
The next product I am considering is a marine 3M 4000 UV which should work but will make it difficult to remove the screws but not impossible.
I don’t just want to use the standard sealant I use which is the Trempro 645 for this application. I do use this for coating screw threads along trim. The awning I don’t want to keep messing with and screws removed from top of arm show a lot of rust so need to make sure water does not get in.
Any other suggestions?
