[TheForge] rusting

[Grant Marcoux]

Bill:  Rust Stop is really easy to use.....allow the piece to rust
naturally, brush on a coat of rust stop and allow to sit for 20 minutes.
Brush on a second coat and allow to sit for 24 hours.  This gets you a true
black.  Grant

Thanks Grant.  I'm always looking for "easier" when it comes to
coloring.  Heating the metal doesn't fall into that category although I
usually heat anything I'm trying to rust quickly. When I darken with
Birchwood Casey among other brands  I've tried, I've been very pleased
with some of the results, like I said before, blues, gray, greens,
browns but rarely true black.  The Rust Stop sounds like a viable method
even though it may mean an extra step. Bill
