I've used both with good results, as bow finishes. The min-wax products are top notch.
I think a good urethane finish is under rated when compared to other more "durable" type finishes that folks use on their custom or handmade bows. The ease of "touch-up" or refinishing a urethane finished bow is not something to overlooked, as it's easily done by anybody, and it won't cost an arm or leg to get it done. Also, I find the finish more than adequate in protecting my bows in the field. No finish is 100 percent and all have their drawbacks....it's just a matter of deciding what is more important to you as the owner.
