1968 and Gelcoat
First off. I will be gelcoating my car. My question is as follows,
My car was ar 2nd Generation Restoration in Walpole MA about 5 years ago. I had to pull it out. I've been doing the work myself. I am getting ready to put the body back on the chassis. The back half of the car was primed at 2nd Generation, I have sanded it but wonder do I need to completely remove all the primer. It is epoxy primer. Ther was very little body work needed. I hate to remove the primer if not necessary. Standard at 2nd Generation is well known for his quality work. We did discuss the gelcoat . Strip it back to glass or ok to gelcoat over it?

For what it is worth:
I ONLY apply gelcoat on BARE fiberglass with nothing else on it other than Vette Panel Adhesive in the repair areas where it was used.
And IF mat and resin were used in a repair. I skim coat over it with VPA.
But that is how I do it but do as you wish.

If you plan on leaving the epoxy primer on and spray polyester gelcoat over it, I would at least spray a vinylester primer over the epoxy.

AS per what is written on the product information page for the product linked in post # 4.
QUOTE: For epoxy, follow the steps above - however, note that epoxy laminating systems require a tack free surface. Increased heat up to 120° F will speed this process. Remember the adhesion comes from the epoxy. Test the bond between the primer and your epoxy blend to assure good adhesion.
So as I was told when I called....as long as the epoxy has cured and can be sanded....the VE primer would work...BUT I am not advising it due to as I wrote. I do not do it that way. But do as you see fit.

That's what I did and after blocking that, Slicksand. Clear is no bargain to spray but GC has to be the worse.
