Can I ask you a question? Have you ever run a business, or any part of a business where profit and loss decisions must be made? It would not surprise me if your answer is no. ANYONE with any knowledge of profit and loss can EASILY see the problem in risking destruction of a multi thousand dollar machine for a $100 job.

If you still believe that this is all a big bunch of hype, I would invite you to stop by your local auto a/c shop and ask them how many systems use this stuff, how many have been ruined by it and if they are willing to risk their recovery equipment without checking for sealant first.

For the life of me I can't imagine why anyone could be so bull headed about something that is experienced and observed in every auto a/c shop in the country on a regular basis.

Unbelievable!
