Thanks folks, for posting good information here. Shelly and I know we want to fiberglass our teardrop, and then paint, or something. Hopefully, we will be near that step in late Summer.
This will be my first time with fiberglass, and I was worried about getting the finish good enough for auto paint. Think Monstaliner may be what we were looking for.
Incidentally, I once owned a Chevy Corsica, and at the 13 year point or so, the original paint was showing some issues. I spent a Christmas vacation painting it gold and black, ultimately using 12 rattle cans of Rustoleum hammer finish. Cut up paper shopping bags for masking, and used Harbor Freight masking tape. Came out great, and the hammer finish really made it forgiving of ripple, rust etc. (Sorry I don't have any pictures showing the surface detail--trust me, it's hammer finish.)

Lived in Los Angeles at the time, and, after painting this, there were certain neighborhoods where some of the young guys would smile and give me thumbs ups. Found out later, evidently, a lot of them got Corsicas from their Grandmothers and tricked them out. It was a thing.
Sure, the black paint faded after that (Rustoleum never recommended using their paint this way), but it still wasn't bad when I moved to New Mexico four years later and, out of necessity, traded it in for the (4wd) Wrangler.
