I fully agree with you that anything that says stop leak or blah blah blah in a parts store is harmful to your system.
I also agree about dye. Dye should be a one time install. It remains in the system. Dye in the system is more like oil in the system. An AC system that is overcharged with oil will flat mess stuff up. It can damage the compressor. Why do Jeeps runs snorkels to the air cleaner? To prevent water in the intake an hydro locking an engine. Too much oil or dye in the system can cause the same effect to the compressor.
A normal AC system will lose pressure or refrigerant over time. The molecules can flow through the rubber hoses and the compressor shaft seal. If a discharge is slow, no oil is really lost. But if every time the system is low somebody adds oil or dye, it ends up with an oil overcharge.
Another problem with dye is that some are water based. Why do we vacuum out our AC system? To make the boiling point of water lower than ambient temperature. It makes it boil out any moisture in the system at room temps. Why does this matter? Because moisture in the system can cause the orifice or expansion valve to freeze (the divider between the low an high side) thus reducing performance and secondly, H2O and refrigerants produce a byproduct know as acid. It eats and corrodes your system from the inside out.
I have worked with r1234yf a decent amount. It is for sure over the top expensive. I will say though that the specs and the performance expectations are no different than the original R-134a specs were as far as the automakers
claims. R-134a was really bad in the beginning and car temps at the vents inside were really 20* or even more warmer, even in Michigan. The transition from R-12 to R-134a was rough from a tech to customer standpoint. In fact, at first we were told that R=134a would only cool to 20 to maybe 30 less than ambient. Yikes. It did not cool well in the beginning but the engineers caught up.
The Acura RL had a condenser that re-wrote the AC world IMO. I have to look back at how it worked. I do not remember all the specifics but one of those cars would make any girls nipples stand tall on any given day in any climate when R-134a still sucked compared to R-12.
The tech with R1234yf is that it flow liquid from the condenser through a cooler that is simply low pressure vapor or gas from the evaporator to help pre condition it for better cooling.
I think they were further ahead of the curve on this refrigerant change as I cannot say that I can get into a car and tell you when blindfolded or with a temp gauge that it has r-134a or r1234yf. I do not live in the desert though.
I can tell you for sure that I could get into a car when r-134a first came out and tell you the difference between it and r-12 even on a modest Michigan summer day.
In the end. It is all political BS for sure. R-12 may or may not cause ozone damage. We are not sure because we never tracked the ozone before something like 1974. The thing that alarmed me about R-134a that I think that most people are unware if is its risk for respiratory issues..... So, think about that. I crashed my car... I am hurt.... My AC system puked... the air I just breathed was full of **** that can make me not breathe.
I once again reiterate. Too many politics involved in all this stuff.
R-12 kicked a$$ for cooling. We have gone downhill since and made stuff more complicated and expensive.
Best advice. Take the top off.

More to say about AC.
The small cans at the store usually have stop leak and a bunch of dye. The stop leak and dye are not a refrigerant gas and will reduce cooling capacity. Every ounce of non refrigerant is one less ounce of the cooling gas that will be in the system.
Eventually these non-gasses will build up and there's no way to remove without replacing expensive parts. So don't use that crap.
And yes, the R134 imported from China may not be as pure as the USA gas. Watch what you put in your AC.
I'm hitting 39* out of my vents on a 110* day. That's called spitting ice cubes! That will make the old lady say "I'm cold"
Lets talk about the new AC gas, R1234yf and how sucky it is. And it's expensive too! I was recently told the GM spec is 58* out of the vent with an outside temp of 86*. What kind of crap is that?
It's because the auto manufacturers are getting pollution credits from the EPA to use the junk. It's at least 18% warmer than R134.

Also, I recommend against the small cans of R134. A lot of it comes from China and it's not that good. Expensive to buy it that way too.
The 30 lb can is 100 bucks and I get the product of USA stuff. Makes a difference.
Get a good refrigerant scale and only add what the sticker under the hood says. Vacuum for an hour or a bit more.

Old lady wants to take the boat out tomorrow. It's going to be over 120* in that Hoover Dam canyon.
My poor truck towing that heavy boat over a hot mountain pass and down into the canyon at 120*
I keep my turbo boost down to keep EGT's down.
Make sure the AC is up to it..

The reason I posted the Lake Mojave stuff is a lot of you guys have boats.
I've actually boated all over the place. One of my favorite lakes is Bull Shoals.
If anyone does boat/fishing vacations, it sounds a bit nutty, go to the desert!
There's a really big fish hatchery at Willow Beach that supplies fish to all the lakes around here.
On the entire 67 mile stretch of Lake Mojave, I counted about 15 boats, a few jet skis and maybe 3 boats fishing. The rest were water skiing, pulling tubes or just cruising.
Imagine, Saturday. The 4th of July. Pulling up to the boat ramp and it's empty. At 8:30am. Not one boat launching except me. Clean bathrooms with flush toilets. Shady picnick tables. Palm trees. A store and nice paved parking lot. Maybe 1/3 full.
A great place for a boat trip. The average depth is 75 feet with no underwater obstructions that I have ever seen. No floating logs to ruin your motor. The water gently flows downstream and always very smooth.
Historic stuff from the original building of the dam up and down the lake (river?) (locals call it The Boulder Dam still)
With so many things closed right now, this is NOT closed! The pass only costs $25 for the week.
So, air up the tires, grease the wheel bearings and let me know, I'll meet you there! Bring your fishing gear and a sharp fillet knife for the Striped Bass, Channel Catfish, Rainbow Trout, Largemouth Bass, Black Crappie, Common Carp, Smallmouth Bass, Bluegill, Green Sunfish, Tui Chub.
It's one of the best kept secrets around.

4th of July. Spent the day appreciating what hard working Americans built for our survival and recreation. 96 deaths is the "official" number of people who died building the dam, real numbers are way more than that.
Down in that canyon, it's 120* down there. We had to keep our phones in the cooler so they worked. Not kidding.
First we went to Lake Mojave. Amazing such a great boating place is so lightly used. Everyone heads to Lake Mead.
It's 67 miles long and most of it is in a fairly narrow canyon. Excuse my video, I took it while driving and had the shakes from celebrating the night before!
It's about 50 miles of this, smooth water in a curvy canyon. Doesn't get any better.
Then we got to the Hoover Dam and Pat Tillman bridge. Since 9/11 they restricted the area. Us and two other boats figured, piss on it. We aren't looting or damaging anything so this was our 4th of July peaceful protest about keeping us out of previously enjoyed areas. We went about a quarter mile past the do not enter line. Not gonna let the terrorists win.
The bridge is 900' above.
You can hear the warning alarm going off telling us were are in a restricted area. This is all I got before my phone overheated and shut down.
Then part two, the fireworks. It was a solid 35 minutes with the best finally I've ever seen. This stupid little town spends half it's budget of fireworks! Better than Las Vegas, Denver ans Chicago combined. (I've seen the 4th fireworks in all those places)

Happy Birthday America
May you well survive both the scourge and the illusion of disorder you see writhing and threatening before you.
“ Tell me not, in mournful numbers,
Life is but an empty dream!
For the soul is dead that slumbers,
And things are not what they seem.
Life is real! Life is earnest!
And the grave is not its goal;
Dust thou art, to dust returnest,
Was not spoken of the soul.
Not enjoyment, and not sorrow,
Is our destined end or way;
But to act, that each to-morrow
Find us farther than to-day.
Art is long, and Time is fleeting,
And our hearts, though stout and brave,
Still, like muffled drums, are beating
Funeral marches to the grave.
In the world’s broad field of battle,
In the bivouac of Life,
Be not like dumb, driven cattle!
Be a hero in the strife!
Trust no Future, howe’er pleasant!
Let the dead Past bury its dead!
Act,— act in the living Present!
Heart within, and God o’erhead!
Lives of great men all remind us
We can make our lives sublime,
And, departing, leave behind us
Footprints on the sands of time;
Footprints, that perhaps another,
Sailing o’er life’s solemn main,
A forlorn and shipwrecked brother,
Seeing, shall take heart again.
Let us, then, be up and doing,
With a heart for any fate;
Still achieving, still pursuing,
Learn to labor and to wait.“
