Lots of products out there being used. Most body shops use a certain system provided by local paint company. It depends on what deal they strike, as this is a big money maker for both parties.
Some shops may specialize in European car repair, and they might use a system from Sikkens or they may use Glasurit.
Many production shops use PPG, but some may strike a deal with Sherwin Williams. The stakes are high, and the signing bonuses are real for shop owners, as a good production shop can generate huge profits in paint sales alone.
Now, do it at home guys use everything under the sun. But to get best results you will want to use the products that have good support. Nothing wrong with PPG, Akzo Nobel, Sikkens, Glasurit, Nason, just to name a few...

I use the same manufacturer for all products from the sheet metal to the finish. Find a supplier you feel you can trust, ask questions, ask for recommendations and follow his/her directions. My paint guy has access to the manufacturers "hot line" for problem resolution. He got the formula for my Edsel from the manufacturer when none of the charts and books came up close. The tech guy at the factory came up with a perfect match for the Jonquil Yellow.

Thank you for your reply ,What I am trying to figure out is if the products formulas are changing,It had been 6-8 months since I I last shoot any clear coat and it smells different and I am having problems with it curing ,I did a complete on a tacoma pickup and I waited a couple days started cut-n-buff ,it was still soft so I wet sanded and waited a week, went back to buff and it was still soft in areas where it was thick and had body work done I had heat to start shooting but due to the fans bring in cold air it got cold fast in the booth, I waited between coats till it was tackey stringy and the temp had risen enough to shoot ,I did a tack coat and 2 wet coats had one small sag by the rear side glass channel small no big deal ,I hit with 800 to let it gas out and still could smell a strong odor of solvents but not what I am use to smelling ,As far as I know I have always used urethane clear but after reading on the gallon can it said acrylic urethane so my question is how many types of urethane base clears are there or has it changed formulas any help would be appreciated not interested in brand names just the difference in formulas

Nice work!
I think its all Acrylic Urethane. At least that's what I remember on the Clear back in the 80s, when I was looking at the front of the can.
Sounds like the weather got the best of you. Which is really terrible.
If the paint hasn't kicked by the next day, it probably won't...
I remember Glasurit has Slow, Med, Fast, and Polar Hardner.
This Polar Hardener was for cold conditions, and would not flow at all in a warm environment. We only used it in primer so it would kick faster, which you weren't supposed to do...
There are others here with lots of experience, hopefully someone can chime in.

There are a lot of clears out there and some can be quite different, especially on the mix ratios of the activator.
You either used bad activator, or the wrong mix ratio.
