Fiberglass question

[IronAnRkst]

So I built a custom console and speaker box for my truck. They are both built completely out of MDF, but I was planning to cover with fiberglass just for cosmetic purposes when I paint the interior. My question is since they don't really need the glass for strength do I need to use cloth/mat or would it be fine to just cover with resin?

Just use the resin. I do it all the time. Just sand it smooth

Resin works well for hiding seams and sealing the edges but you need to prime the whole thing with a good quality (preferably urethane or epoxy) primer before you paint.. regardless of whether or not you glass it.

Thanks guys, that was the plan but wanted to make sure that would be okay.
