I am building 4 of the Rythmik 15" subs. My first one, the test mule, is almost done. I have been trying different techniques on finishing it on the different sides. It's made of 3/4" baltic birch wrapped with an outer layer of 1/2" MDF. It is primed with BIN sealer/primer which was sanded smooth with 220, then 320 grit. I used a black enamel paint over that. Brushing it one doesn't work unless you have gorilla sanding arms. Spray can method works fine, but I needed to do lots of light coats, one after another. I found that sanding and recoating seemed to make no difference. Just using lots of light coats gave me a decent smoothness. I also tried using automotive rubbing compound on the paint, followed by Johnson's Paste Wax. That actually gave the best results. Has anyone used that method for their finish? It makes sense in that enamel was the automotive finish of choice for many years.
What other choices are there for a good satin black finish?
