Cross tie and fence post treating

A better formula than what works for 100 plus years?
Man just go with what has proven to work. In 100 years you won’t care about those still standing fence posts. lol

Thanks. The last round I went too light on the red diesel (maybe I was being cheap) and didn't get good absorption.

I have been applying a 60/40 mix of Borax and Boric acid after I cut them as a pesticide, going heaving on the open ends then letting them dry. This was from an old Navy recipe. Good news is both of these can be found cheap at Walmart in roach pesticide and cleaning powder.

Chinese saw mill will pay for itself in no time if I can get the treatment process down.
