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.
