good luck on the canopy!!!
And don't forget to use a good flouride rinse after brushing! Prevent's decay, plus it leaves your model minty fresh!
As an afterthought, at Wal Mart in the cosmetic section they have a set of 3 nail boards with some kind of vynil covering on them.. a fine, extra fine and smooth as glass one... those worked great on the HH-65 canopy I was working on... went from one to the other.. the last one had it about as clear as future would have had it... put some future on and it looked even better!
I sanded with the abovementioned grits first... then went to the sticks...
