Far better to simply replace all of the o-rings at the various connectors, it's not so difficult...... there's no quick fix to anything..... do it right the first time and keep movin on!!

Not all sealants are created equal. There's no chance that Cryoseal will clog anything. But, the leak has to be slow enough, and in the right place (for example, Cryoseal won't address compressor shaft seal leaks).
A common weak spot for these cars is the evaporator. For many of us, who have neither the skill set nor the patience to replace an evaporator....and who are unwilling to pay our mechanic $2000 to do it...a quality sealant is the obvious choice.
