So I was reading an article about tiny homes (one of my other interests), and saw a picture that instantly made me think of golf ball dimples...
Would the holes in the material, along with the smooth edge of the material lead to a similar golf ball dimple situation?
The backsides of some of these have bumps, so they aren't holes but pockets.
It's for drainage and hydrostatic barriers, or some such architectural/engineering technical mumbo-jumbo that I didn't follow. But they are made of plastics, rubbers, and high impact polystyrene, depending on application. Miradrain is one of the companies/brands for this stuff, and that's who's product is in the pictures above.
I haven't been able to find exact dimensions on this stuff, but it appears as if the plastic core of the product is around 10mm thick (for the shiny mettalic one above). So perhaps you could shave off the bumps on the back side bringing it down to like 3mm, and then use something like vinyl to attach it to the surface of the roof, rear pillars, and rear quarters? Or even better, to your belly pan?? Or would these be too small to achieve the same result as golf ball dimples? I know that dimples on the bottoms of the newer VW's, Audi's, and Lexus' have much bigger fist sized dimples on their belly pans.
I look forward to your thoughts.
