Do some searches on Clark's Bamboo Forum. Some of the guy's over there do some awesome wraps. Some use a mixture of Varnish and Walnut Alkyd.

Hope it's OK to link to these.
I haven't tried it yet but the walnut alkyd is fairly inexpensive. I do have an 8 oz. bottle and could send out an ounce or two if anybody is interested.

Definitly not taking anything away from Mike's beautiful wraps.
