Finally got to the top of the queue at the upholstery shop and the new tonneau cover is now in use.
I had it done in "Sunbrella" marine cloth. This is the stuff they make ski boat tops with so it's water proof, should hold up to the sun, and wind. It looks nice too
It cost me just over $400 so the price was reasonable. The other quotes I got were double that and more. It could lay a bit flatter but seems to be smoothing out after a couple of days of use.
While writing this, another thought came to mind. I've got the full soft top (top, bows, side curtains) that I bought from CRL, Fargo, ND when I bought my car. It's been used twice, maybe three times in all the years I've had the car. It's made from Haartz cloth in the color black. Nothing wrong with the top, I just don't use it and it's been laying on a shelf in the garage that whole time. If someone with a CR is interested in a soft top, I could be persuaded to part with it for a reasonable price. Just a thought.
