3M works perfectly fine with me, am satisfy with the heat rejection both with moving and stagnant car, its miles better than my other 98% irr tint on the other car. kinda regretted goin for the brand, should top up few hundred to tint both cars 3m but kinda wanna experiment to c what are the differences so yes, if you do have the budget, go for reputable brands who shows u tser values, it's the most important thing for heat rejection.
