A coworker of mine is a bee keeper and he said they used to use bee propolis to preserve early strativarious (spelling?) violins. Its a thick substance honey bees use to plug up holes in there hives and its from tree resins which help preserve woods from microorganisms and decay. I guess it could be thinned with alcohol or somthing. I'm going to be building a bass this summer and I was wondering if anybody has experience with this or has found it to be less effective than other methods of preserving. I'm a rookie on the luthier stuff but it just seemed like it would be a cool way to personalize my experience further. All responses greatly appreciated!
