I've seen professional tint that looks like ass, too. The only tint I that never looks bad to me is factory tint. So if I used Llmar myself, would your brain explode? "It's good tint, but you did it yourself. AHHHH!" The tint I'm buying is lifetime guaranteed as well, I"m just doing it myself.
I'm afraid I could talk until I"m blue in the face. Ten years from now, if I had tint that went bad, sure enough someone would say, "See I told you!" I've got tint installed and paid for it, but I want to give the DIY a shot. And I'm not very impressed with their install either, yet another reason why the pros aren't always going to do it right.
