## Description

Product description

Review: GOOD PRODUCT and, an inexpensive way to resolve an evaporator leak. - I admitted, I was a little skeptical about the effects and effectiveness of this product but, I am impressed. A leak on the evaporator coil is the last thing you want to hear when facing with an Auto A/C issue but, if you are interested this situation, concider using this product. Easy to install and after more than 6 months, it's holding pretty well with no side effects noticed.
Review: Waste of time and money! Buy another brand! - A really bad product! It has no instructions whatsoever. Comes in a box with a QR code on it that links to very vague instructions. It says to add this product to a fully charged system. I did that and the back of the syringe popped off spraying the liquid everywhere. Luckily I had eye protection on or it would have gone directly into my eyes. The back of syringe blowing off seems to be a very common problem with this product according to other reviewers. I wasted $30+ on R134a because it is just going to all leak out now in a few weeks. Almost all of the other leak repair products say to add the leak repair first then charge with refrigerant.
