Re: [DML] finding freon leaks

[Christian Williams <delorean@xxxx>]

Walt,

I recently had my A/C serviced. The guy who recharged the A/C put some
blacklight sensitive dye in along with the freon. That way if I have any
leaks in the future I can just use a blacklight in a dim garage to find
the leaks.
