Re: Tips in sanding polyester resin/ paper gumming up
I've used wire wheels on a drill or angle grinder to remove paint from fiberglass and it doesn't damage the glass as long as you aren't to aggressive. Angle grinder with a fine wire cup brush works best for that. Might work for the wax, or may just spread it around. What about removing the wax with ...

Re: Tips in sanding polyester resin/ paper gumming up
It's not cured completely. Assuming enough hardener was used, it probably got dew on it before it fully cured. It will eventually cure, but it needs time and heat will speed it up. You might try putting a black trash bag over it to absorb the heat on a sunny day.

Some of the chrome can be too tightly adhered to be removed with brass wool or a brass brush. Like Paulus said, steel wools is bad because it can leave rust stains.
