Hello,
I typically use Minwax Wood Filler to fill in un-necessary holes in drums. My question to you is this:
On larger holes (such as the bass drum post, or on the "Pearl Style" arms/brackets), after I sand the wood filler so it's level everywhere, what do you think of using a polyurethane on the wood filler itself?
I have tried this on some cheaper, non-vintage drums. My theory on doing the polyurethane is that the shell is obviously subject to a lot of vibration. Polyurethane soaks into the wood filler and makes it stiffer, harder, stronger, and "one" with the rest of the wood fibers around it. After using several coats of polyurethane on the filled spots (inside and out), it became just as hard and stiff as the rest of the shell.
I was always worried that on larger holes (1" or more), that the wood filler may just eventually "vibrate out" one day.
What do you think?
