Steve,
I used Polytone on a Kolb Firestar (Ag Cat Yellow) and used regular rubbing
compund on all the upper surfaces. Don't rub too hard on the tapes or
anywhere the ribs or braces are under the fabric. You have to rub kinda hard
on the open spaces like between the ribs to get the gloss you want. Mine is
not anywhere near Aerothane, but it looks great. Then I use Mothers Carnabua
Wax on it.

I just finished a Rans S7 with Aerothane and I am done with Polyfiber
products, at least the color coats. The Aerothane stains easily, is
difficult to apply, because the mannual is wrong and you are left to remedy
your problems on your own. And it is extremely expensive, over $3000 on the
S7. The Poly Brush and Poly Spray seem to work fine and do the job getting
the aircraft ready for the color coat.
