I need some feedback on Freeze 12 or Hot Shot.  I still have R12 in my a/c system.  If I opt to go the freeze 12 route can it just be mix w/ the R12 and oil in my system.  I don't want to convert to 134A unless I have too.  It looks like I will also need to buy an adapter kit if I go with the Frezze 12.  Any and all feedback is welcome.

hey bud i am a ac business owner in dallas texas and unless you have problems with the system i would stay with r-12 the replacements for 12 dont work and if you feel that you need a recharge of 12 try to find some virgin r-12 vacum the system and weight in the correct charge also i have found that insulating the evaptor box in the engine bay by the left rear of the engine by the headers will drop the evaptor temp some 10 to 20 degrees  i used some dyna mat good luck Brent

Hey Joe. If you go back into the past threads you will see there has been much conversation and opinions on this topic. My professional opinion is to go with what the system is designed for. If you still have R12 in the system you must not have a very big leak. Why mess around with changing over to anything else? R12 is available however pricy, but is your Vette worth doing it right?
Here's a chart to show composition of different blends.

 Note, Freeze 12 is 80% 134A. Hot Shot is 1.5% Isobutane...............

Hope this helps.

Where is the best, safe place to buy it?  I have it in my system, it just needs a re-charge.

guys check on ebay or biz rate just do a google search for r-12 and all kinda of options come up i seen many drums of 12 on ebay i would buy a big jug compared to a 12oz cans your systems probally hold about 2 3/4 to 3 lbs or freon just check the data tag on the evaptor housing i know it might be pricey and might not need that much this year but what about next year and the year after and so on r-12 will be harder to get as time goes by ps just be carefull not to get burned try and meet and chech the weight and empty 30 lb jug weights around 5 lb so a full jug should weight about  35 and so on and as a ac contractor i pay 30 a lb for mine good luck Brent

A drum is way more than I am will too spend right now.  Thanks for the info.  Drum will be a last resort.   Last time I recharged it, it lasted me years.  I don't drive the car a whole lot. 
 
I messed up, last year the guy who serviced my home A/C had some and I waited to call him back.  He will not return my phone calls now.

Last year, I rebuilt/restored my A/C entire and decided to stay with the R-12. All that I read about Freeze 12 and other substitutes was not good, Freeze 12 uses propane as one of the main ingredients..... and there seems to be a 50/50 chance that it will cause compressor failure!
  I looked on Ebay and the local Craig's List and found a ton of it available. On Ebay, they require the buyer to provide proof they are certified to work on A/C.... Craig's List has/had no requirements. I posted on my Local forum (Arizona Corvette Enthusiast) and found a member who had 7 Dupont brand 12oz cans and I bought all for like $20 per can. It seems the going rate is $25 to $50 per 12oz can.
Sorry, my remaining cans are not for sell, but maybe check Craig's List online in your area, you are bound to find some there. If you have a shop service your system, make sure they put in your expensive R12 and not substitute it for the Freeze 12, which shops will use and most have on hand. Just make sure you trust your AC tech!

Good luck!

BTW: 81 toy, Good idea on insulating the evaporator, gonna wrap mine with Dynamat this weekend!Thumbs Up   Phill's Vette2010-09-03 18:58:00

OK, I got some R12, thanks to Larry.  Can someone send me step by step instructions to re-charge.  Cannot find my old notes.  I have the origianl service manual, will read, but I am sure it was written for shop workers back in 79.  When I paid someone the last time I did it he put the R12 in at the top of the dryer, there is a fitting near the larger line that goes into the evp/box.  I do not have a site glass.  Fitting near back of compressor also, goes to top of dryer, large line.  3rd fitting on small line that goes to the condensor, front of car. 

May have the name of my parts mix up???
