I agree with Wayne's approach to wing walk application. Another benefit of using the liquid variety (actually, very thick & needs a lot of stirring) is easily repairable when a spot here and there chips off. This happens on my LH side since that's where I climb up/on, but not on my RH side since I usually fly solo. Throw-away chip brushes work well; I think foam brushes would not.

I removed the stick-on stuff from my Alon when I stripped the plane, The stick-on material is made of a layer of some type of plastic sheet that has adhesive on one side and grit on the other. The plastic sheet can trap moisture between the plastic and the surface of the wing. On my plane, every rivet under the wing walk material had some light surface corrosion forming around it where the plastic material formed a tiny "tent" around the rivet head. This corrosion was not bad, but left alone, it would have gotten worse. Also, the wing walk material was lapped over the edge of the center section spar cap, and had started to cause corrosion on the top surface of the spar cap. I think that the paint-on type wing walk material would allow any moisture to escape and possibly reduce the chances of corrosion. Also, the stick on type on my plane was an absolute nightmare to remove. Chemicals won't touch the plastic sheet that it is made from. I had to use a heat gun and a putty knife to scrape the stuff off. Randolph makes some pretty good wing walk paint, and that's what I plan to use if I ever get around to painting my Alon.Best Regards,
