I replaced the nut yesterday. The Stew-Mac nut slotting gauge was a real help. It makes the cutting of slots go a lot faster. Since this is a temporary nut replacement, the strings were not lowered to their lowest position. I tend to keep them at least 0.030-inch above the first fret as a temporary measure. For this temporary nut, I used plastic.

I also purchased lacquer shade #28008, Ford Engine Red, by Model Master TM Custom Lacquer System, at Hobby Lobby to see if I can match the body paint color.
