I have a bass that has a gloss finish (polyester I think) over cocobolo facings. When the bass is left over time the finish gets a misting or fogging effect that can be wiped/polished off, yet it always comes back. Can anyone explain what is causing this and whether there is a permanent remedy? I had the bass refinished some years back, but it still does this even now. Was the cocobolo too green when the bass was made or is this a common problem with cocobolo? Thanks.
