Buddy of mine has it. Its very bright.. But he says if you dont get up there and pressure wash it every now and then, it will get foggy and algae or some green stuff will start to grow on it... He got the clear top though...so its Completely see through. He says he blocks it in everynight since smeone can look into his trailer and see everything he has in there. But really if someone wants the stuff they're not going to look inside first...How would they know you have a see through roof? Now they make a translucent one where you cant see in if your looking down from the top of the trailer.
