I'm doing the ceramic coating on my side glass in my convertible while the glass is out and easy to do(even though it's harder to put back in without scratching it). But I found a company that will make me a charcoal tint rear window plastic for my convertible and am going to order one of them when I get time to install the top. that and A/C should help leep the convertible semi cool in Floridahahellitshot weather.
