Anyone know a good place to get Lexan windows?

[Plavan]

I want to get new lexan quarter windows (frameless). I would like to know of a good source other than GT Racing. I will never do business with him again. So any other company is welcome

Try www.spektrproducts.com. No personal experience but they seem to carry a lot of lexan products.

Wow, that stuff's expensive. It seems like you could simply cut raw Lexan for the side windows and rear quarters.

In trying to duplicate the Saratoga Top I have found several Lexan sources, below is the best price I have found for clear.

You can get raw lexan 1/4" x 48" x 96" $ 146.81

Lexan is a complete pain in the butt to work with compared to Plexiglass. It must be much hotter to contour/mold, 310F vs. 180F for plexiglass. It is much more impact resistant than Plexiglass but it is softer and scratches much easier.

If you have the contour / profile coordinates of the piece you want to duplicate, you can get blocks of hardwood CNC'd and then apply thin felt to the hardwood mold. Then you have to hang the sheet in some sort of oven (I used a friends silk screen business oven) slowly get it up to temperature and rapidly get the lexan sheet on or in the mold. Lexan contracts/shrinks sort of unpredictably so you have to leave at least three inches on all sides to account for this. I should say that's how much extra I had to leave for my first Saratoga top attempt.

To rework/restore the finish of Lexan and Plexiglass, the finest products I can find are from: http://www.micro-surface.com/default.cfm?page_id=1

I have used Micro-Surface products in the past to restore several aircraft windsheilds.

Are any of the lexan/polycarbonate/plexiglas products actually scratch resistant? I've seen some (for other cars) that claim to be "hardened" or something but are there any of them that could actually be used as a roll-up side window without getting all scuffed and scratched?

There are some coatings that can be applied to Lexan to decrease scratches. Plexiglass is much better at resisting scratches than Lexan. Plexiglass can also be restored to optical clarity whereas Lexan cannot. Lexan can be improved greatly once scratched but it's never like new.
