underwater led

I'm going to be installing lifeform led's tomorrow. Anyone have any tips or words of wisdom? What is a good sealant to use for gel coat?
Thanks!

Measure twice, Seal everything with 4200 or 5200 , chamfer the hardware holes after drilling to eliminate spider cracking with self tappers go in.

You can use a drill bit a few sizes larger than the hole you have made and run the drill in reverse to make the Chamfer. Definitely chamfer. Or you WILL have spider cracks. Maybe not right away, but the screws will create small one upon entry and before long, they will get big and ugly...

I would do all the above, plus putting some tape over the surface before you drill seems to help stop chipping.
