Sealing unpainted plastic crank baits'

I bought some square bill's from Shelts on Amazon. Turns out some of them leak. Is there a best way to seal the seam and hardware entry points?

I’d assume an epoxy finish would work. Personally I’d use a rod building one like flexcoat. If you want to do a bunch and want a hard finish bar top epoxy is very durable

A fast and easy way is clear nail polish. "Hard As Nails" works good. Just use a thin coat
