## 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.

*by R***S on 27 October 2022*

I took a long shot on this one hoping I could distress some tiles I painted with a copper paint. It worked to a point but not enough. I think you need paint with enough metal particles that aren’t covered with the varnish within the paint for it to work. Fortunately I tested it off the wall. So, check the composition of your paint if you don’t want to wing it!
