Laminating resin + microballoons will float in fuel I know. One might
thus try tinting it red or such, cure a little chunk of it and file
down to proper sized ball with a hobby file and/or Dremel tool. Paint
over with pure tinted resin. Systemthree.com has genuine epoxy
tints. Suspect that the "universal" tints available in paint stores
cheap will do too, as only a few drops needed. Test for long time in
fuel of course.
Best,
