Got a newbie question on sanding fins. How many times should I seal and sand fins to get a good looking and good flying rocket. I think I remember the Stine book says three times, but want to make sure. Also, how do you know when the fins are good to go and are there any other fin tips or good advice prior to installing them? I already have a fin jig made so at least I know they'll go on straight (lesson learned as a child).
Thanks in advance!
