Re: Duramix Fiberglass Panel Adhesive--Any Good?
Wayne, do you know if what SMC was made out of? Was it gelcoated, etc.? Terry

Wayne, do you know anything about when Rockwell was making panels. I have seen General tire insignia and rockwell printed on fiberglass pieces. TerryComment

It is not gelcoated, but consist of Layers of smooth resin over a sandwich of fiberglass. This gives it the slick finish.Comment

MFG the major original supplier of fiberglass panels was sold to Rockwell in 1970. Rockwell made panels for original production and for years after for the service parts sold over the counter.Comment

Re: Duramix Fiberglass Panel Adhesive--Any Good?
So, no panels had gelcoat on them? Was genite sort of short chopped fiberglass with resin? Was the resin a polyester type? Just wondering what they were trying to improve.
What people see as gelcoat was just a thin layer of resin without fiberglass, regardless of SMC, black glass, or genite? Thanks for the information. TerryComment

Re: Duramix Fiberglass Panel Adhesive--Any Good?
No gelcoats on anything but some 54s. The Genite panel is hard to describe. It is more like the old fiberglass panel except that it has no or little fiber at the surface. It is usually light grey like the SMC but does not show the marbleing effect like SMC. On the car and sanded, the surface looks more like SMC, but the material is harder. It is in effect a bridge between the two. I am not sure but the Genite material is probably a polyester base like the old fiberglass, with some different type fillers but cast as a wet resin. SMC as I understand it is in a sheet form and this is placed in a compression mould and is thermoset. This produces the sandwich effect with a very slick surface. The reason that it is hard to bond is that it has release agent as a component of the material.Comment

Re: Duramix Fiberglass Panel Adhesive--Any Good?
Now that you described that genite, I had a panel of that and now know what it looked like. I had a hard time trying to tell if it was SMC or Black glass that looked more like Gray colored glass. On the face of it I couldn't see any strands at all. On the back side, I recall seeing the tell tail signs of short strands that sporaticly came to the surface. It was very smooth on both side though.
I would think that all the panels regardless of there type would have used a release agent as the first step of preping the mold. I guy I met that was making fiberglass panels for a MG project described it as: 1) Sprayed release agent into the mold. 2) Sprayed gelcoat into mold. 3) Sprayed fiberglass and resin in with a chop gun.
I was told to always wash the outside of the panels before sanding or using any solvents to get any release agent that could remain on the panel. I was told that solvents could transport the release agent into the panel and sanding could leave traces of the release agent on the panel also. There is a lot of stuff that floats around about preping the panels due to so many paint failures. I would like to know if there are less paint failures with the later panels and whether the paint on those cars lasted longer because of the improvement in the panels. Thanks, TerryComment

Scott - Lord corps FUSOR line has some very nice handling two part epoxy bonding adhesives that work well with SMC, Genite, polyester, or dissimalar material bonding like metal to glass. Also, there is one that works well as a filler for bonding seams after the bond is complete, and if I recall, you have a few choices on the kick time involved, for larger panels such as hood surrounds, more time is required.....CraigComment
