Anyone know what the side panels are actually made of? Mine need slight repairs (cracks chips and repainted) Believe this forum said not to use fiberglass? Assuming normal body filler is fine? Any special kind of primer?

In 1982, the hoods were referred to as "sheet-molded plastic". A cousin to the fiberglass panels used on early Corvettes of the 1960's.

We did a repair on the side panel of our 8010 last winter. Ran over a piece of metal doing a custom job for a pipe yard, the front tire kicked it up and broke the bottom three inches and latch off of the side cover. My son's buddy does some Auto body, he bought a fiberglass repair kit from the Napa store. After several applications over the course of a couple of weeks it turned out very nice. And then I cheated a little bit taped off the area where the decal had gotten torn up and just painted that black after a rattle can of corporate orange on the panel. Looking at it from 10 ft away you couldn't tell it had been damaged.

We used fiberglass 'bondo' with no issues for decades. If you ever saw one burnt - it looks identical to fiberglass no matter what they called it. Just a caution  if one ever cracks it must be reinforced somehow on the backside as well as the outside as the repair will crack again.

Definitely will need reinforcement on the backside, and probably wise to drill out just past the end of any cracks to relieve stress & prevent the crack from progressing (same principle as brazing a crack in iron).

My preferred way is to scuff the coating off on the back to give a good key, lay a couple layers of glass & then before the resin cures add in a thin sheet of aluminum (old drinks can usually fine for smaller, sub-6" cracks, or thin gauge steel pop riveted in place to do up bigger damage) and then lay a few sheets of glass over the top of that to seal it all in.
