* Typo correction. That's SSR Cryo-seal, not SST (in my other post), in case anybody wants to check it out. The product is produced by SSR International, Inc in Georgia. BTW, this company does a major business in Iraq for the US military.
* A very helpful and knowledgeable service center and distributor for Mercedes retrofitters is Improved Chiller Engineering in Oklahoma, web site at
www.acstopleak.com. I'm plugging this business because they've helped me with accurate information on several occasions (when they didn't make a dime), and have done more ac retrofits than anyone else I know.
