Hard wax application is a lot easier than some make it out to be. John
Murray gave me a little demonstration, but it's pretty much a common
sense thing anyway. Just keep moving and make sure the rotation is
correct when you get near trailing edges and control surfaces. It
works beautifully for me. I'm not scared of it, but I do have some
respect for the danger it presents near trailing edges. Just take your
time and think before applying.
