That sounds like something I would like, think I will try a gallon, if it holds up and doesn't mildew it would be worth the extra money.I use Penofin Oil (Brazilian Rosewood Oil) it is 99% uv protection and has a mildewcide and fungicide. The down fall is it's rather expensive running $35 to $45 per gallon. However it holds up very well.
Forrest:I would avoid using Brazilian Rosewood products - it is a CITES Appendix I endangered species and though there are legal exports, the demand for Brazilian Rosewood and its derivatives such as oil (used in the perfume industry primarily) is so high that it continues to drive large scale illegal logging.
I would rather not be part of the demand that drives this industry, but of course each person must make up their own mind.
