My 1990 300D 2.5 Turbo has a small leak in the AC. It seems to be located under the dashboard, an unholy place to work on. Therefore, I was happy to find that someone makes a sealer, Cryo-Chem International (www.ssrintl.com) called Cryo-seal, which they seem to sell only to EPA certified shops in kits of a half dozen or more.

I would like to know whether anyone has any experience with this product, or if there is an alternative similar product that might solve my problem. It gets too darn hot in Miami in the summer and I will be forced to drive (oh, the shame!) my rather reliable 89 Hyundai Excel, which has a cold AC.
