So, on the Dye stuff, should I see a colored gas coming out of the system? The stuff I found at Walmart yesterday said it had a UV dye in it, and was meant to be used with UV light, but it didn't even give a hint as to what to look for, or how to go about doing it. Is there another product out there that I should be looking for?

 

i think that stuff is meant to be used with a black light. if you don't already have one, pick up a small fluorescent black light from a retail store or hardware store, or even spencer's in the mall. when you turn it on, the dye will glow, pinpointing the leak. as an added plus, the black light comes in real handy at partys

 

get a uv light if you can but there real expensive,
a black light will work but wont show as much and i suggest using it at night,

good luck
