Is the trim piece removable? Is so, maybe a smooth 3D printed replacement or some filler w sanding to eliminate the pattern on the stock part.

I like this idea from a purely aesthetic standpoint. Post up some pics in a thread of its own once you have the finished product.ām having charcoal and orange aquatraction made for my doors. You could do same for this area. Seadek sells small pieces you can cut to fit.
