Nothing wrong with the dyes other than being messy. In some cases that is about your only option for a slow leak and if your line set is long and ran in hard to get locations (above a ceiling, inside a chase, etc.). I had one case where it was ran up a chase to the roof above the 5th floor and above the ceiling in a mechanical room and a laundry room at a hotel. I found it above the ceiling tile in the laundry room. It works where others fail. If you can't find a leak with it then you don't have a leak.
