Tru-oil you say? Yes, I've used it with my auto spray guns to apply a 50/50 tru-oil/mineral spirits mix for a nice gloss finish on my varmint 22x47 Rifle. It's held up great for 10 years now. It's glossy but still not a high mirror shine. I was thinking of trying min-wax "wipe-on poly" out of my spray gun, or, maybe buying gloss Duracoat. (??) No, I don't want to go with 2-part 3M or Dupont auto epoxy paints for $75-$100 cost being I'm only going to use it once before it sits on my shelf forever & goes bad. I'll revert back to a $20 bottle of tru-oil before I blow $100 on a single gloss auto coat. Any ideas?
