Works great.
Big fan. I have used this product for a while and easy to use. My only critisism is the included directions. To be honest, they suck. A 1oz. bottle contains four treatments. I can tell you there are basically three ways to use it. If you are working on an A/C system that has no dye then inject 0.25 oz. into the system. If you are working on a vehicle that does not have UV dye added and are replacing a component (such as the compressor or condensor). Either add 0.25oz of dye directly into the new part, before installing it or mix 0.25oz. of dye to 8oz. of PAG 46 and inject the recommended amount of oil to the system, after the repairs are completed. If the manufacturer has already added dye to the A/C system and you are performing a repair or refill service, mix 0.25oz of dye to 12oz. of PAG 46.

Did the job
The dye works but not so easy to inject. I don't see being able to use this more than 2-3 times as it is all plastic. 1st time for me but it takes a lot of strength to push it into the system. My compressor glows. Thank goodness I don't see any other leaks 2004 Suburban with +-200' of tubing and hoses in a dual system. Why can't dye come in a can like freon.

Very bright
This stuff works! I was able to quickly identify the source of the leak. It shines very brightly under a UV light.

Good...opened product.
The UV dye seems like a good product. However, the packaging is not tamper evident. The first bottle was leaking out of the package when it arrive. I ordered a replacement and it was opened already. Leaking UV dye is never a great surprise.

Looks like top quality dye, helps you find leaks
Didn’t get to use it. But it’s pretty straightforward. You need a UV light to detect this leaking from your ac system.
