## Description

Mastercool 90935 A/C Repair Epoxy

Review: Perfect for bonding aluminum when welding/brazing isn't an option - This stuff really does contain aluminum! I used it for a client project that needed to be electroplated, and the metal components could be welded or otherwise soldered together, so I used this stuff and voila! Super strong bond and no electroplating trouble at all!
Review: Works great! - Works great! I had a hole in a high side AC line on a Chrysler Pacifica. After repair the system is sealed and holds pressure.

## Questions & Answers

**Q: Would this work on a evaporator? Need to seal a small leak**
A: Yes it would . However, if your evaporator is leaking in one spot due to old age and corrosion, the rest is not far behind. Replace it. If you punctured the core and its in good shape then by all means.
