I used a wad of Proofide , and melted it into the Upside down Brooks , in a warm oven.

That was . in the 70's , other than that, it did not get re treatments..

warm it soaked up the melted waxes, and they of course re solidified at room temperature ..

still used the Plastic Bag, made slick bearing surfaces for the legs in the rain pants..
& I didn't worry when it was not in the tent with me, camping out.
