Jon I don't know what it is but I wouldn't bother with it. You've got your car back to a shell, and spent hours on repairs don't skimp on materials, in the scheme of things even Glasurit is cheap compared to the labour in fixing an old car. Have look at Lou's 66vert on the members page this car was done properly, 14 years ago and it looks like it was painted last year, this car realy turns heads but it's a dead stock C code vert, with nice wheels, nice paint and body work, I think the engine got no more than a set of rings. Paint and body are the single most important things to get right on a resto, the rest of the stuff just bolts on, you can change an engine in an afternoon, but if the paint plays up your going back to steel again. Everyone should forget about quick engines and gold plated steering racks get the paint right first, the rest is easy you just bolt it in. And don't think acrylic won't do you any harm either, there are plenty of old painters out there that can't breath, from spraying NC and Acrylic for years don't worry about that. If your sensible with 2K you'll be fine considering you'll only be doing one job. Ventilation is the key.
