Hank, are you a Jedi at the LE sanding board wrist flip? Someday I do
hope you can look at my HP-24 wing and see what you
think.................the LE is indeed a very difficult area!
I'm far from bored today: I've already sanded the primer down to 150,
applied several brush dabs of primer to some small craters, and now am
about to make up a bunch of Mousebgone................which is how I
pay for my soaring addiction(s)
Cheers,
Brad
