Input:
Works as advertised and in line with the Hoppe's namesake.  The white film it leaves behind is fine for firearms - its just an indication where the Dri Lube has been sprayed, and while not visually pleasing, the metal-on-metal parts it coats aren't readily visible anyway.

Only con of this product is the smell.  Personally it was a little overbearing, but no big deal.  Definite recommend.
