I know this is probably one of the dumest questions, but i need to ask it. I have watered down the elmers wood filler per information i have found here. Painted my fins on my vagabond and executioner even though that rockets fins are ply, dont know if that was needed? Anyhow, when you sand the filler after drying, do you sand it down basically taking it all off with say a 220 or 320 grit paper until you see barewood again? and do you guys fillet it on the lugs and fins to make it uniform and neat prior to paint? I really could use some help, as i would like to complete these two bad boy rockets i have gave so much love making perfect. gosh i sure do enjoy this hobby more as a grown man more than when i was a kid!
