Fullerplast was/is a very durable finish. The downside was that it is a nasty carcinogen and I think an air supply was recommended as opposed to a common organic filter respirator. There were other similar performance 2 part polys like the PPG auto finish that we used for R/C airplane models for it's resistance to methanol-nitromethane fuel. Most of these polyurethane 2 part clears were highly toxic and the mfr's recommended air supply systems. I painted my car with one of the PPG polys and used an air supply. Not a trivial thing.
