## Questions & Answers

**Q: Does this epoxy do well in heat? Specifically exhaust/muffler heat?**
A: I used to heat to remove the epoxy when it didn't hold as well as I had hoped. I don't think this would work with a muffler.

**Q: What material would be best to mix this on?**
A: I use piece of cardboard. It works, though it’s a pain mixing it. Make sure u mix it well.

**Q: will this fill pinholes in welding? I am looking for a product that will easily fill the little pinholes and look (and react) a lot like the steel**
A: Great question. I think it could fill the pinholes, but am unsure if it will look like the steel. You may try painting over with matched color.

**Q: Can it be used for a/c aluminum coils repair with 410A refrigerant?**
A: No, It really doesn't work ona lot of items.  We tried.
