Hey there, Greg. Your question sparked another thought I have. This was the process I used on these:
1. Primer, in this case Gunze GSI followed by a light sanding.
2. Sprayed a layer of Testors Glosscote. I do this to smooth out the piece even further. I draw out the gloss, so no sanding is required. If a spec gets onto the piece, I lightly sand.
3. Spray Alclad Brass.
4. Add a final seal coat of Testors Glosscote. Mainly to protect the paint because is somewhat delicate.
5. Apply a wash.
Step 4 is where it got interesting. I didn't do that this time. Either the hot lacquer melted the clear underneath or, the spray issue I mentioned added a sealant to the Alclad. As I mentioned at times it was spraying clear. So either that was lacquer coming through, or some type of suspension in the paint. The brass paint mixed together with the clear making them one. I didn't have to apply the final sealant. I got a high gloss out of this. It was kind of cool it worked out that way but a person has to be careful that the piece doesn't lose too much detail.
None of this is here nor there but I thought interesting to note. Is it a fluke? Maybe.
