When I bonded my replacement body panels to my 71 I used Lord Fusor epoxy adhesive. This stuff is like nails, but the downside is that it doesn't play well with polyester based body fillers. Apparently there is some incompatabilty that can cause a loss of bond over time. As a result, the tech data sheets from Lord recommend using an epoxy primer prior to applying any polyester based fillers.

Consdering I need to fill my body seams with something, and that I'd prefer not to go through the effort of priming these areas first, it got me wondering - does anyone make epoxy based fillers? All of the products I looked at are polyester based.

What fusor were you using? I used 100/101 ez. The 127 that I glued my header bar with wasn't compatable with polyester filler.

I used the 127

I agree with HobbyPoor use the 3M 05885 it's a superior product to the Fusor and does not have compatibility issues with polyester filler.

There are some marine products that might work. West Marine has a few epoxy resins and hardeners and also several types of fillers of different densities that can be added to the mixed epoxy.
Check them out at www.westmarine.com or see 2009 catalog pages 224-225.

You can bevel all your seams just like you're prepping for a glass repair and use epoxy resin and mat as a filler and add strength.
You should be able to get that finished enough so that after the epoxy primer you should need no more than some filler coats for hand blocking.

Epoxy fillers are out there, but far too pricey for most, or you can mix your own.

Thats exactly what I did, ground out excess 127 fusor, bevel edges, then the West Systems 105 epoxy 206 hardener and mat gives me a good solid foundation. The pic is before mixing and applying a West Systems 105 epoxy and 407 filler mix to fill small imperfections and pin holes over that. Then I would prime with epoxy. Lots of other good forum threads on how to glass your seams if your into that. Other than that I would think you could use any one of a number of the epoxy adhesives as a filler to fill your seams.
