RE: natural wood color filet
I use some Elmers wood putty, it is tan colored and comes
from Lowes or Home Depot. As it comes, it is pretty thick. I add a few
drops of water and stir in a bunch of micro balloons.
After you apply the mixture, wet your finger and
slick it down/smooth it out. If you need to sand after it dries,
it sands great. Cover it up with epoxy, CA or water based
polyurethane before painting.
