"Glazing Putty" for balsa?
I can't believe how bad this is frustrating me. Over the years I've tried a LOT of filler materials from spackling to micro balloons to some really crazy concoctions including auto body glazing putty. Nothing sands easy enough to feather out without damaging the surrounding balsa. Every filler I've tried is always too hard for my taste. I finally found a filler I'm really happy with. Elmer's Carpenter's wood filler "natural" color and it's awesome but still doesn't feather as easy as I'd like. I need something to use for that final sanding to smooth and feather. Any suggestions for an EASY sanding final feather option? Have I said "feather" enough? A nice random orbital sander in a size for R/C would be perfect but I haven't seen one of those yet....;)
