So I am replacing my battery trays on my Charger 496. I notice the bilge area the batteries sit in is not completely flat. There is some high and low spots that cause the battery trays not to sit exactly flat. As a result, the batteries rock in the trays because of the high spots. It’s not real bad but enough to notice. Both areas are just enough area to fit 3 batteries. Just to give you an idea of size. So while I have these out, I’d like to flatten these areas out so the trays and batteries sit nice and flat. I was thinking of sanding but that seems like a lot of work and doesn’t really address it not being level all the way back either. Is there a self leveling epoxy or something I can pour or spread into those two area to level and flatten those areas out. I wouldn’t need much more than a 1/4” at the worst spots...if that. I’d want it to adhere well, be durable and last, and be water proof in the end. I also posted this in general bassboat topics as I wasn’t sure the best place. Thanks.
