Glareshield
The easiest and quickest way is to use some sort of tubing as previously suggested. I decided to make a lip for my RV-6 because I thought it would look better. I used a piece of .025 aluminum I had in my shop, scribed a line for the curve of the glareshield, measured about an inch or so from each side of the line and cut it there. Then I bent it into a U-shaped channel, made notches so I could form it to conform to my glareshield curve, and flush riveted the flange of the 'U' to the edge of my glareshield. This gave me a one inch lip down from the edge and covered the edge. I then put automotive headliner material on the glareshield and wrapped it down around my lip. I used automotive vinyl roof contact cement (very strong) to glue it in place. If you use this stuff, make sure you have it in the right spot before letting it set down, because you won't be able to move it. After three years of flying my RV-6, it still looks great....in fact I don't think I've ever seen a glareshield I like better. Headliner material is a foam-backed material that comes in a huge variety of colors and textures. And it's not supposed to fade in the sun. I got mine at a warehouse here in Cincinnati that sells foam and other stuff. It is also sold here at an auto upholstery shop (where I had my floor carpet edged). It took me about 3-4 hours to make the lip and less than an hour to cut and glue the foam-backed material on. A little time, creativity, and a helpful mother-in-law will give you an interior that looks like a BMW. All of my interior materials and sound proofing(not including the Oregon Aero leather seats) weigh less than 5 pounds and is very quiet and warm in the Cinci winters.
