I'm going to have my M20J repainted. The original wing walk is a self adhesive non-skid material. I kind of like the uniformity of it's appearance, but it is starting to get bubbles under it in places. And, it has to be removed if the inboard fuel tank access panel ever needs to be resealed. The painter recommenced applying grit to the paint before it dries and then painting it black afterwards. I'm curious what others have done. Pictures great if you have them handy. Thanks.
