Mike,
I bought a cockpit cover and wing/tail covers from airplane-covers.com. The covers are coming up on two years old and still look very good. The fit was excellent and they come with a standard two year warranty or a three year warranty for Sunbrella fabric. I use the cockpit cover 365 days a year and the wing covers for approximately 5 months a year. I paid a total of $511.90 in December of 2007. (including shipping) The cockpit cover covers all the glass and the fuel caps...
I'll second the recommendation for the Deerton, MI company Airplane-Covers.com. I'm on my second cockpit/fuel tank cover. This second one, unlike my first which lasted outdoors from 11/04 'til it started to shred 8/06, is made of Sunbrelle. This fabric is a big improvement over whatever the first was made from.
My second cover was more expensive, but I was given a small credit d/t it's premature demise. It is on all year and has stood up well since I purchased it in 9/06. I have no idea of how many more years I'll get from it, but there is no sign of failure yet.
I like it better than the cover Ron has because it covers the entire rear window. I was concerned the leak I had was coming from the upper seam where the window meets the metal. The cover I have is Cessna 150-2 Solid Color Sunbrella Cover with Accent & wing Wrap Cost $294.95. They sell other (smaller area coverage) covers which I wouldn't recommend, but may be sufficient for your purposes. Take a look at their web site.
One modification that I made to my cover was to replace the bungee cords which hold the (partial coverage) wing covers which cover the gas caps with 3" wide webbing and associated Fastek buckles. I made the suggestion to the company to d/c the bungee cords because they were insufficiently rugged and did not stand up to several months of stretching. I got the webbing off of my first Airplane-cover.com so other than my time, there was no additional cost. The company did offer to repair the bungees, but I knew what I wanted and did it myself. I have spoken w/ the owner and have found him responsive and receptive.
The sun is intense and destroys most lesser fabrics not up to constant exposure. Whatever company you go w/, I'd advise u2 spend the extra bucks for the better quality material.
I have no experience w/ wing covers, just know they are costly and that's why I have avoided them. I agree frost is a pain to remove, but doesn't take too long-perhaps just as long as it would take to doff and don the covers?
