Now, I have jumped forward a little with the right gauntlet. It's been primed with a 'filling' automotive primer already and I'm in the process of filling all the little pinholes in the resin. I'm using a scale modelling product called Mr Surfacer. It's kind of like a paintable putty. It's acrylic resin powder mixed into a lacquer paint. You brush it into small cracks and gaps, let it dry, and sand it smooth. I haven't sanded it off yet, but I think that it's just covering up the pinholes, rather than filling them up. I'll be going at this gauntlet on Sunday with an orbital sander and some sanding sticks to see how my pinhole filling job went. If Mr Surfacer doesn't do the trick, I've heard that you can also thin down some PVA (white school glue) with water and use that to fill pinholes in resin. It sands smooth too.
My left gauntlet is not going so smoothly. I applied two layers of fiberglass mat to the insides of these things, and the heat ended up warping the left bottom gauntlet half too much. I tried correcting it with heat, but it just won't stay in the shape I need it to close flush with the upper gauntlet half. I got Christian from MOW to send me another gauntlet half, and it came in last week. Right now, it's at school setting up after its first fiberglassing. I made sure that it will cure up in its proper contour using a form. It's only going to get a single layer of mat on the inside and a few strips of cloth on the edge where it will be hinged.
