Hmm. So about $100 per pound lost, which isn't too bad. Especially
compared to speed mods like gap seals etc, which cost what? $1000 per
mph gained? Something like that? It's been a while since I
researched that.

Gap seals are dirt cheap. I can get gap seals for my ailerons that are
really just tape. Around $100 for the kit. Several companies sell gap
seals for the flaps of Cessna's. Maybe $300 for a typical 182.
