What are you using to protect the under side of your fiberglass ?

I brush on POR-15 for the underside of the glass. I will scotch brite is also so it has some bite.

I actually have a bit of POR-15 left.  Brush on might be easier since my body is mounted and I wouldn't have to worry about over spray.

Thanks Dale!  What type of paint?

I have read that some use an epoxy primer before the paint and some use Rustoleum bed coating.

Hello

What are you using to protect the underside of your fiberglass body?  You know the part you dont see.

My main concern is water intrusion from the back side, It appears to be raw fiberglass.

thank you
