I've cleaned off the old wing walk material and would like to replace it w/something less punitive, but still effective at providing non skid and protecting the paint (new paint!) I'm planning on using the clear or white wing walk material, and in strips instead of the large section. Any comments? Secondly, my flaps are depressed down about 1/8", likely from being stepped on during boarding/deboarding. Any comments before I tackle that? thx, Tom ________________________________ Message 2 _____________________________________ Time: 01:12:53 PM PST US From: Bradley Kidder Subject: Re: TeamGrumman-List: Wing root airflow question --> TeamGrumman-List message posted by: Bradley Kidder Tom: When I bought my AA-1 three years ago, I had to remove old painted wingwalk using a heat-gun. I put on an adhesive wingwalk after painting the wings, but these came off within a year. What I did this time was buy a quart of black exterior paint and mix in a baggie of anti-skid. The baggie was designed for a gallon of paint, so I put the whole thing in a quart and the consistency worked out perfectly. After masking off and applying four layers, it looked good. Works even better.

Did you think about the airflow over the wing root when you were laying out the non skid stuff? It may not even be necessary, but I just don't have any facts to work with. Tom I did buy a bag of non skid stuff, but haven't decided how I want to approach it yet. A foot wide, three foot long non skid "mat" was on it when I started. It took a heat gun and lots of scraping to get it off. It was clearly too big as it went from the flap almost to the leading edge. How much is enough? Is there an optimal pattern? Or a more optimal pattern? Tom
