`Rustoleum makes brush paint, which can also work, but it won't set as even... at least it never did for me. I've never been good at making even brush strokes, to lay flat. That, for me, was more frustrating than all the work involved to spray. But, I've never been a painter.
If you're good with a brush, then it'll take far less work, than to spray
Jim,
Yeah, you probably should be lending those Acadians out to newer players in an honorable gesture of helping to foster the perpetuation of Cajun music.
