Shedding weight this winter. What thickness of Lexan should I buy for the windshield ?
What is mar resistant ?And you want to spend the extra for "mar resistant" - which will be a special order for most suppliers.
I was cautioned against any thing but glass for the windshield as it fogs up easily.
I'm offering an opinion based on my experience. I've had both and in my opinion, I wouldn't spend the extra money again.Well that settles it - no point in explaining it, is there !!!
From what, humidity or exposure to UV ?? General purpose polycarbonate (lexan) does not have any UV inhibitors in it. Acrylic (plexiglass) does. However, you don't want plexi for a car windshield !! So if you're going to use polycarb, you want to order it with A) UV inhibitors and B) a scratch-proof or mar resistant coating. These are readily available BUT will likely NOT be stocked by any local supplier. Average delivery should be about a week.
I know this not because I've used it but because I sell engineered plastics.

Fogs up from humidity.
It’s 36x72x3/16 for $209That's sign material. It will have UV but no abrasion resistance. The rolls are very large and the material isn't very thick so it should flatten out reasonably well - especially if you can lay it in the hot sun for a while.
Price-wise I don't think that's great. I sell a whole 4 x 8 sheet for $230 plus tax Canadian !!
Look for a local supplier under "Plastic - sheet, rod" in your yellow pages. Are you close to these guys ??

Sabic are global distributors so would be more likely to have it and if not, they would have regular shipments coming from manufacturers so they should be reasonably priced.
We don't call them "scrap piles", we call them "offcuts". When someone like yourself needs less than a full sheet we sell you what you need and keep the pieces for other people like yourself. It saves you money and we get a sale. If you think they wasted your time well ... I'm glad you didn't call me!
Wow you get offended easily.
