Old thread but hoping it still lives. I just got through using 3m 5200 quick cure to mount my solar panels with those big wide flanged ABS mounts to the flat roof of my canned ham 2024 t3 .032 aluminum
.... I prepped with acetone but that's about it.
Now I'm wondering if I made a mistake. I read something that 3m recommends a special primer... of course now I read it.
Are my panels going to fly off?
“If choosing 3M adhesive/sealants, understand that the repair may not last
as long as you would like. 3M Marine Adhesive Sealant Fast Cure 4000UV has
the best anchorage to clean aluminum, without the use of a primer. If you
prefer to use polyurethane adhesive/sealants like 5200, Fast Cure 5200 and
Fast Cure 4200, you will need to use two part epoxy primer called EC-1945.
This primer may be difficult to get because it is an industrial product and
is not readily available in most Marine supply stores.”
