That makes me sad... how does it compare to actual leather in TX 100 degree days?
Just a suggestion, and I know the outside temp is still in triple digits, but when you park, tilt up your sun roof and crack your windows.
This will vent a lot of heat and have the interior temperature be closer to what the outside temperature is, instead of 20 to 30 degrees F hotter.
The biggest killer of interiors (read: dashes, seats, etc.) is the cycling of extreme hot and cold, especially extended levels of heat.
I know I'm repeating myself here for some of you, but as a medical device engineer, we have to do accelerated aging testing on all our products before public sale to prove our products are able to have a shelf life of "X" number of months or years.
How do they do that? We use a formula that calculates a temperature that would represent an extended length of time, say maybe 3 years. That calculation will determine who high a temperature and for how long to equal a product sitting on a shelf or in a warehouse for 3 years. These accelerated tests usually last only about 6 weeks at about 150° to determine shelf life for 3 years.
Now considering the above information I've just provided, what do you think you're doing when you lock up your vehicle with all the windows shut for hours at a time, every day in temperatures hot enough to fry an egg?
You are prematurely aging all your interior components!
Something to think about.
'nough said.
