## Questions & Answers

**Q: Is the 'Rust Activator' the same as the green (copper) and blue (bronze) activators?**
A: No. One is for Rust and the other is for green or blue, depending on which paint you use as a base coat. There are three base paints and two activators.

**Q: Will this work on my powder coated galvanized mail box?**
A: Use a self etching primer first. Then it will bond the the powder coating.

**Q: This wont work on new metal roofing thats not painte would it ?**
A: I believe it well work. Purchase a smaller quantity and test it first. I use it to get a rust effect on modern masters metal effects paint that has actual ground metal in it.

**Q: Can I use this on corrugated metal panels from Home Depot to get a rusty look?**
A: As long as you use the iron paint first, you can virtually rust any material.  I’ve used it on wood, glass, ceramics and metal.
