I have had the qtec cover king covers for my tj going on three summers now, can't complain at all just a little hot in the summer. Anyone that was with me during ocean city jeep week can vouch for the fact my jeep was "full" of mud and water, I just took them out and hosed them off, they came out like new. I usually have the top down in the warmer months without doors, when jeep sits for a couple of days I do loosely put the top up. This may cut back on surface as I haven't had any fading issues
I can vouche for it. So was his tranny.... girlfriend... him... ateering wheel.... and about anything else that he had haha. One more thing. I got the best top ones on amazons scratch and dent. I love them. Only bad thing is if it rains and you dont have the top on you have a swimming pool in the seats because they are water proof.
