I need to top up the R12 in my 82.  On a 100 degree day, it is only blowing about 86 degrees.  I have read a lot about converting to 134a and most everyone agrees it is not as efficient, especially in our hot Texas summers.

I have not tested for leaks yet, but will (my son is a mechanic and will give it the UV test).  Everything works fine, just not cooling like it did in prior years.  

Has anyone had any long term success with "Freon-Don" or "Frost-King" or "Artic Air" or "SERCON" ect?

Anyone going to Carlisle would you please let me know what vendors are currently selling and their contact info?

R-12 can still be found if you hunt around, a LOT.  I local shop near me keeps a supply on hand mostly because his personal "fleet" of old cars use it.  I plan to have him go through the a/c on "BLKBRRD" before heading to Ft Worth.  Don't know anything about the products you mentioned.

And you're right about converting to R-134.  Did that shortly after buying "The Beast" and regretted doing it when running through Nevada after the Carson City Gathering.  The a/c just couldn't keep up with the desert sunshine, no matter how fast I drove...!!!  ;-)

Definitely would not "convert" to R134 as it will not work as well as R12 because the condenser is to small and the compressor is really too small, even for R12.  Not sure why they thought the Corvette would be easier to cool than a passenger car as they have larger compressors in their other cars.  Don't know anything about the products you mentioned but I wouldn't add any non-R12 gas.  You should get about an 18 to 20 degree drop across the evaporator.

I read years ago that it takes about a 7-8 ton capacity A/C to cool a full size car.
