Restoring a grill? repairs and paint?

72 Grilles are a little tough to find around here, so I've had to resort to put them together in piecemeal fashion. Here are some in progress. The second photo is a completed grille.

To repair the structure of the grille, I use Slo Zap glue. It is a gap filling, superglue that sticks well. If the gap is really big, I fill it with plastic body filler, sand it, coat it with a light coat of Slo Zap, and sand it again.

The second grille is the one that is in the Demon. It only needed a little graft in the area in the photo. For the graft, I used the same part of a broken up grille cut a little large, then sanded to fit in. Then the Slo Zap.

The other grilles need a lot of help. I have plastic gusset plates Slo Zapped into place that hold the major pieces into place. There is plenty of room at the bottom to put them in without them being obvious.

For finishing the grilles, I shoot a plastic adhesion promoter first. The next step is to shoot the black areas in Rustoleum Semi-Flat black. The names are being changed around a bit, a Satin finish black would work OK, too. When dried at least a day, I mask off the black parts and shoot Rustoleum Aluminum paint. As soon as I get the grille where I'm going to let it dry, I remove the masking tape. For each color, I usually shoot two coats, ten minutes apart.
