Re: 'Regolith' Concern?
I believe that the surface of the Glasliner FRP material is primarily fiberglass and therefore any mechanical abrasion is unlikely to result in the release of styrene fumes. Considering the material is designed for use in bathrooms and other common locations, any outgassing is possible but unlikely.
Based on my observation of the dust produced under intense load, I believe it is a mixture of fine fiberglass particles (potentially irritating but unlikely to be toxic in small amounts), plastic particles from the rover wheels, and dirt from various surfaces.

There is a big difference between "we have not been able to figure out how to do it." and "it's impossible" or "don't even bother." Let's be constructive not discouraging. - PVCMike [more]
