I agree with the last post. I'm building a warbird now, and I just finished 'glassing and priming it. It's not much heavier than an iron-on covering if you take your time and do it right, but on an aerobatic bird like yours every ounce is going to count.

Not to mention glassing and painting is a lot of work. I thought it was easier than iron-on, but takes a lot more time. Drying between coats, wetsanding, etc...
