I'm just thinking... What about flat bellypan with small bumps instead of dimples? Any thoughts? Because in my opinion it's much simpler to glue some bumps to the flat surface of the belly pan than to make dimples in coroplast for example.

Edit: In addition, I have those bumps on the inside wall of Berta's rearview mirrors. Don't know the exact meanning of those, for now. I've heard that cut the noise of the air passing the mirror, but I'm not sure that's the only reason for that.
