## Description

ALUM BOND 6.5OZ/184G

Review: Quality product - This is a good product, I tested it against JB Weld and it adhered better and was stronger. I would expect that, since it is designed to seal high pressure refrigerant leaks, I was not disappointed. I used it to fill gaps, holes, and other flaws in my aluminum boat instead of having everything heli-arced, worked well.
Review: Top notch stuff - I bought this as a hail Mary repair to the front cover of my 7.3 diesel engine. It's got a crack that isn't accessible to weld and replacing the part involves engine removal. The area is subject to 75 psi oil as well as high temperature.. this product was easy to mix and apply and it's working beautifully!

## 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.

I had a puncture in the side of my pontoon boat, on the underside of one of the logs. I applied this material and it stayed in place and bonded really well.
