Glass can be hard to find for an old BMW. When I went searching on Craigslist I almost ended up with an entire car. What am I going to do trying to save two Bavarias? I’ve only got so much crazy. I could have posted a WTB on the forums but assumed nothing would be close and shipping would be expensive. So I made a rear window from .187″ thick clear polycarbonate 60″x22″ from Professional Plastics for $120 bucks.
At first, I was all proud of myself for trying to make the template from the box it came in. You know, reduce, reuse. But I quickly realized rigid cardboard made for hard tracing sitting in the back seat so I switched to some brown packaging paper. After getting a rough outline I transferred it to the sheet and cut with an angle grinder. I did some rough fits, trimmed as I went, sealed it with silicone and wah lah! It looks better than it works. I’m still getting a leak in the rain but I really didn’t use that much silicone and will goo it up in the near future. The impetus for the project was to rid my front yard of a blue tarp’d car. My neighbors have patience but I’m not looking to push it.
