When I used to work with extrusion coating, the cooling rollers we had with
the machine were mirror finish, and the hot plastic would stick to it like
crazy. We had them refinished to a matte finish, I think I remember
something like a 70 RMS spec. Still felt totally smooth, but just not mirror
finish. That's all it took for the plastic to come off very nicely.

Matt,
I wonder if the right kind of ruff might not be better. From what
I've
read some of the speed swimmers are using a type of body suit that
mimics a
fish's skin, reducing drag.

Absolutely right! A little rough actually has less drag. However thats
difficult to get..I believe shark skin has that roughness that reduces
drag.

IF this can be sprayed on it would be a must have

Matt

I'm talking about the outside, not the inside. Several boaters
around here (fresh water) have done so.



This Rhino stuff although very tough is very rough .. I would be
concerned it increases drag of the boat in the water significantly ...
