I have a wood tiller that is made out of a pinkish wood layered with a yellowish wood (sorry, but im not a wood expert). I have sanded off all the peeling varnish or whatever it was on the thing, and have a nice clean tiller to re-finish. What would be the best, high durability material to use to finish it. Sun resistance is key too; the tiller bolts in normally & doesn’t come out easily.
