I hope you're waxing any hardware going into hardwood. It extends
its
lifetime a minimum of 100%.
I sprayed LPS-3, which dries to a waxy film, into the boxes of lag
screws, and I predrill oak and pressure-treated SYP for the shank and
threads, somewhat undersized since the fasteners need to withstand an
estimated half ton of snow and ice on the roof. . AFAICT the hard wood
scours off some of the zinc, so wax doesn't really have a chance.
Are you using tapered drillbits? If you're scouring the galv off it
on the way in, the hardware won't last in PT, anyway. LPS-3 should be
good.
I stopped waxing furniture screws because it interferes with staining.
Ewwwwwwwwwwwww! Wood shouldn't be stained. Use a clearcoat, fer
Crom's sake! /purist But if you must stain, finish the wood first,
then drill and assemble. Pieces of carpet on your drillpress are
friendly to prefinished furniture components.
I spent this morning sanding off a misguided amateur puttying and
staining job in the club's bathroom. On the way home I raided HD's
rack of unpretty PT 4x4's at 70% off. The firewood it will support
doesn't care what it looks like.
Funny, that.
