  Okay, make sure brain is in gear before engaging mouse. In my excitement to
win your "prize" I missed  the sentence in your e-mail already mentioning
the Randolph product, so I don't credit for much new information.

Anyway, I found the can. Here's the info for whomever is interested.
Randolph Products Wing Walk Compound, Black X-1567, MIL-W-5044, Type 2.
According to the price sticker, I bought a quart can of the stuff from
San-Val for $13.25 (10 years ago, figure in inflation). I only used a small
part of it since a gallon covers 60 sq ft. Apparently available in gray as
well as black. According to the label, it's immune to just about anything
except kryptonite and can be applied to just about everything except Teflon.
No website on the can since it's 10 years old. I'm afraid I can't answer
your question about fabric but with the plywood under the fabric I wouldn't
expect much flexing. Anybody in the Seattle area (especially near Crest)
want to experiment with some on fabric?

It's also available in a liquid form that you paint on after masking off the
area. I redid mine about ten years on a metal wing and it's holding up fine.
I'll try and find the can of the stuff tonight when I get home and email
further info unless someone beats me to it. I just wanted to get my entry in
early ;-)

Hi all,

It's getting close to re-assembly time for my freshly recovered Pitts S2-B
I had a question regarding wing walk covering options.  The last time I went

through this, I used a wing walk material from Aircraft Spruce that had a
adhesive backing.  I also installed the metal strip on the front edge of the

wing walk that screws to the leading edge/spar cap strip and keeps the
from peeling back in the propwash.  The problem with this installation is
down here in Texas with our wonderful, hot summers, the adhesive will soften

when the plane is left out in the sun.  Stepping onto the wing walk with any

side loading will then cause it to walk on the wing.  (I don't think that's 
where its supposed to get its name.)  It is also prone to developing bubbles

over time.  What is the best solution to this problem?  You guys in Arizona 
must have figured this one out a long time ago.  I know there are wing walk 
materials that are glued on with a separate adhesive, such as Pliobond.  Any

recommendations?  Any experiences with a fabric covered airplane using a
walk that is painted on (such as the Randolph Products stuff)?
