Lexan windshield finished

Well after about a month the windshield finally got finished today. Went with 1/4" coated lexan from PercysHP.com
First impressions? Total pain in the ass, do not attempt this unless you have another person to help you and a lot of time. On the other hand its bulletproof and weighs nothing so its worth it for a track car.

Step 1- make a template

I chose thin poster board because after having a crappy edge with cardboard it was the only thing that could have enough flex and still be strong enough to not cave in.



Step 2- Cut the lexan

Using some Bosch wood blades and a jigsaw this step was easy, just take your time and it will come out looking nice. Although it needed a few test fits and trimming before it fit perfectly.




Step 3- Mask off the perimeter for paint

This is looks only, but it does help keep the sun out of your eyes when you have no visors.
Again, this was easy but very time consuming to get the right measurements.




Step 4- Painting the perimiter

I used krylon and black engine paint. 2 light coats, then wetsand, then about 5 more light coats and wetsand again. Looks very good when finished and does not let light in.




Step 5- Seal with Winshield

I stepped up and bought the actual windshield sealer for $17 instead of the $3 RTV. I have no idea if it is actually better, I just wasn't about to find out if the RTV was worse.



Step 6- Fitment and mounting

Theres no way around it, this part blows... especially in 27* weather
I decided to use 4 self tapping screws on the bottom and 4 on each side. Self tappers were a must because its impossible to get a nut on the other side of the bottom and side windshield on a 928.
For the top, special bolts from PercysHP.com were used. Thanks to the guys on Rennlist for the tip of using half rubber washers so the screws dont crack the lexan






Step 7- Don't use shitty drill bits

...or this will happen




Step 8- Step back with your now useless and frostbitten hands and admire your work
