For what it's worth, my approach is to have 2 logbooks: one as a "draft" logbook, where I do make mistakes when loging right after a flight, the other, the "official" logbook, where I copy what's in the "draft" logbook. OK, that's more expensive, but it cuts down on the mess, and gives me the luxury of having a spare in case I misplace or lose the "official" logbook...
Cheers
