Your whole car looks great. Good job with the side curtains.
I have made similar curtains and they are pretty good.
I like posts securing your curtains better than mine. Where can I get a set like yours?
From your pictures, it looks like some rain would still get in during high speed driving. I bought some 3mm black neoprene and glued it to the edging on the inside. It helps to fill the gap between the side curtains and the winshield frame, but you can't see it from the outside.
At high speed with the top down, I catch the wind in between the lexan and the windshield and the curtains bow out. For top up driving I have added two snaps which snap to the flap that hangs down from the top on the inside.
I would like any advice on how to get a good seal when driving fast in the rain. I think it might involve something like the chrome wind deflectors we see on the fibersteel site.
