I removed the wrap from a Yamaha Manu Katche Hip Gig kit that was wrinkled. It’s made from luan mahogany I applied a first coat of Mineral spirits and Tung Oil at a 70/30 dilution. Waited 24 hours then a second coat of Tung Oil and mineral spirits at a 50/50 rate. Waited about 72 hours then applied a coat of pure Tung Oil. I’m not seeing much sheen. How many coats will I need to have even a decent gloss?
