I used it recently in very high temps and humidity without any problems. When applying it I used the CarPro applicator with suede microfiber over it. I did change the suede microfiber a few times. Is it possible you were dragging partially cured product over the surface when applying?
I don't think the applicator was the problem. Some areas the product would go on flawlessly. In other areas of the vehicle the product would start to cure almost instantly while I was spreading it causing smears before finishing the cross-hatch pattern. Other areas with a similar amount of product would go on just fine, but never flash or give any indication it was safe to level out. The product wouldn't self level...it would just sit there like I was spreading apoxy and become just about as sticky. The towel would actually stick to the product.
There were also issues trying to level it. I'd apply the coating, wait a minute or so...and it would smear when I'd start to get rid of the high spots. I'd wait another minute thinking the humidity was to blame, and it's still smearing. Wait another minute or two...and it would smear and then harden instantly.
Just curious...
What all did you do to prep the car?
And...
Was this the last prep-product,
prior to the Coating application:
BLACKFIRE Crystal Coat Paint Prep

The car was washed, clayed, and polished with Meguiars UP. I then applied the Blackfire Paint Prep liberally all over the vehicle to make sure the surface was as sterile as possible.
This is clearly a case of the "coating crap-shoots". Sometimes you will get great results. Sometimes you won't. The problem could be anything of a million + 1 variables that aren't quite right.
That's what I'm afraid of. Conditions very so much I'll never get the same results twice and there isn't much use in experimenting. The sad part is I got varying results on the SAME CAR while trying to apply it.
I really hope the product is even half as durable as it claims. If it goes a year, I'll be happy and keep trying to perfect the application. Any less, and I'm going back to Klasse SG or Collinte 845. They all look about the same, easily last 6 months, and aren't nearly as finicky to apply. I never thought I'd say something was more finicky than Klasse...
UPDATE: In the end, I grunted it out and was able to get rid of most of the high spots and hardened smears with brute force. I just hope I didn't remove most of the product.
As already mentioned, I'd put the looks in the Klasse or 845 area, but it does darken the paint in ways neither of the other two will. I did notice some uneven darkening in streaks in some areas and a mottled appearance in others. Not sure what's going on there.
I'd still love to hear some ideas on what I may have done to cause these bizarre results, so I don't repeat my mistakes. I think if I could have just got it to apply consistently and then figure out the right timing for buffing out the high spots, I'll be golden.
