That junk is just shoveling the cost forwards and amplifying it.
1: To properly service, nevermind diagnose, an AC system you're going to need a machine to recover what's in the car, a vacuum pump, a refrigerant scale, a set of gauges and an oil injection gun. An AC refilled with junk in a can will never work as well one that's been properly serviced.
2: To properly leak test a system you're going to need some nitrogen at about 200 PSI and a bottle of soapy water or a high sensitivity ultrasonic mic, or if you're unlucky, some AC dye and a UV lamp if it's a really small leak (like I had to find today on a '12 civic)
3: Any workshop that tests incoming cars with a refrigerant identifier will spot the leak sealants in junk like acpro and instead of paying for just a quick leak test and a service, now you'll be paying for a condenser and a complete system flush before any diagnostic gets done. Modern condensers use extremely fine conduits that get clogged by leak sealers.
4: Refrigerant with stop leak in it is considered contaminated and has to be sequestered and destroyed.
5: Most shops with an automatic service machine will refuse to work on something that has stop leak in it because it gums up the solenoid valves.
Would you DIY your fridge? just take it to a shop, the amount of equipment and expertise needed to do this well is not negligible, and the cost of mucking it up yourself can get astronomically high.
