Where could I get lexan sheets locally?

[Black97civic]

Well, just to let you know, this is a thing I am planning for next spring at the earliest, so I don't wanna piss anybody off, if it's gonna be a pain in the ass, don't worry about it till then when I am ready to buy.

But the thing I am looking for is a full 4' x 8' sheet of MR-10 Gray tinted 1/8" thickness.

I say that I want the 1/8" but I would also ask if you thought that it would be an appropriate thickness for my rear hatch, and rear quarter windows, and if not what size would you recommend, and what would the price be for that instead.

Thanks
