From a post I did in 2021.
"Thought I would share the windshield trim I made. I was not happy with the trim currently available, the shape just doesn’t match the corner pieces. Anyway here is what I did;
Used 3/16” cedar plywood formed by clamping to the windshield and body to get the correct shape, top and bottom pieces. This took weeks by wetting, bending and the letting the wood dry and starting over. The plywood pieces were left wide, about 12”, which made the bending easier as there are compound curves involved. The bottom piece was particularly hard to bend and get to conform. The sides pieces where easy, basically straight but they do have a slight inside/outside twist to them. Once the plywood was formed, it was cut into strips so it could be slipped/ inserted into the corner pieces. To get the triangular shape to match the corners, I epoxied sheet metal strips .040 thick to the cedar, then used a flexible body filler to create the bevel. Sanded and epoxy primed the pieces. I have yet to cover the pieces with a chrome body wrap but a practice piece worked out very well. After the windshield is installed I will epoxy the pieces to the windshield with a urethane adheasive.
This was a huge amount of work to say the least. Just my luck it will all blow off at speed!"
Update 2024: Pieces are now complete with chrome wrap. What a nightmare. Plan to use butyl, windscreen to boby and then urethane adhere the trim to the windscreen.
One question: Were the original corner pieces polished or a brushed finish?
