Hello Arthur. I would sure like to try your new stripper. Am I within the first six? You have my address. Also, when we spoke awhile back, you mentioned you were working on a metallic/bronzing-like ?powder? or something that can be added to water-based clearcoats for plates. What's the status with that? Any progress? I get great-looking results with laquer, but I wonder about longevity and laquer is soooooo soft.
