I am at the point where I should prime the wheel pants. Will primer stick well to the gel coat on the parts or does this have to be scuffed up prior to priming?
Thanks
Thanks
Priming should be done just before painting, so I only put primer on the areas where I applied Fiberglas - to protect the epoxy from UV. I left the rest of the gel coat intact for the paint shop to prime and paint. ��
You should fill air the pinhole before primer. Search this site for methods, Dan Horton had a good post on that. Read your OP and noticed you have jel coated parts.You may not have any pinholes, count your blessings.
There are definitely pinholes in the gel coated parts .. you can't really see them until you have sprayed primer then they start sticking out like sore thumbs
Remember too that the outer grey layer on the newer fiberglass parts is just tinted epoxy
The grey coating on the outside is a layer of colored epoxy and most likely thickened to minimize pinholes. .
will "Filler Primer" take care of the pin holes?
Lots of ways to do this from drywall compound to high build primer to an auto body "icing" or "glazing" product or even traditional spot putty which all fill well with varying sanding difficulty and different degrees of strength and stability. I would put down a layer of epoxy primer first so that your finish is well adhered to the wheel pant before pin hole filling although most of these products can be applied right to the fiberglass. I like this Upol product that fills well and goes on like pancake batter and is reasonable to sand off.

The key to pin hole filling is to sand the filler all the way off leaving only little dots in the pin holes. Depending on your method it may take several coats to completely fill the holes
Scott, you out there? Kindly identify the gray coating...exactly what is it?
I am pretty sure it is Duratec.

Traveling right now so unable to confirm.
