What ya-all know about refrigerant dye?

I bought a kit at oriley that came with a black light flashlight and dye, but no way to get it into the system.

I ended up using a seringe and put it in through a schrader valve. (System was completely discharged)

Worked great once I got the dye in.

Btw don't walk around the house with the flash light on in the dark. Eeeeeeweeeeee!

In the immortal words of Star lord "looks like a Jackson Pollock painting.
