I don't know how I came across it but a couple weeks ago I saw a video on YouTube I believe where a guy was adding tape strips to a prop for an electric to balance. Seemed like a good idea for electric motors but wouldn't work for glow as the fuel would dissolve the tape glue pretty quickly.
actually tape does work reasonably well with non electrics... (I used it in the early 70's even) since the prop is ahead of any fuel (or fuel spray) the tape does actually stay on pretty well.
(although I'd go a tiny bit light on the tape and add a coat of dope to make it permanent.)
it's not a great idea to remove material, but (ONLY my opinion!) unless you're removing big hunks, it shouldn't be an issue.
