The right plastic is a nessesity. I'm still running with the same film from back in 2005. (wow! 15 years! I'm getting old.) I'm planning on changing it this year as i think that it is getting old enough to be effecting the UV transmision negativly.


wow, 15 years it's lasted? That's amazing man, not even storm damaged? ... You should tell the company that sells it, they'd be over the moon I bet!
