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

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.

Leaking bottle
Not sure if it’s a common issue but one of the bottles I ordered (1 of 2) ended up leaking during transit but other than that all good

Muy bueno
Lo compré para revisar una posible fuga en el aire acondicionado del carro y cumplió su función. Es fácil de usar y el colorante ayuda a identificar rápido por dónde está el problema. No soy experto y aún así pude usarlo sin complicaciones. Muy útil para detectar fugas antes de gastar dinero de más en el mecánico.

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.
