Having attempted this myself, I'm sure that this is a good value at $450, but being out of your area and thinking about doing this myself again this year, I'm wondering how much time a professional would allocate to buffing and waxing a painted glass glider (no gel coat damage)? I just waxed the wings last summer by hand and I got discouraged because it took me so long. If I knew how long it would take you, I might not feel so inept spending so much time (or I would feel really inept and seek professional help.)
