This is why I powder coat. Works great.
I found a 1.5inch chunk of alumenum in the junkyard. Drilled a 1/2 inch hole into it and stuck a old soldering iron into it. My old lubesizer is bolted onto this contraption, works like a charm.
Sorry my caps lock in the keyboard is stuck, have to figure out how to get this unstuck on this old computer.
Cheers
