Types of paint and a question about finishes.

[IT Cowboy]

I was going to put this in the paint forum but I thought it would get better visibility and responses here.

I am looking at a 72 C10 that is yellow and I spoke to the owner last evening and he told me about the truck. He was telling me that the truck was repainted at some time and they used a paint that is very hard and resistant to rock chips (urethane or acrylic? IDK). He was saying the person that sold him the truck explained that the finishes at the time were just not as deep and shiny as todays finishes and they had a slight bit of an orange peel to them. I will try to verify when it was re-painted and with what.

I know, not too much information here but my question is this an excuse for a possible dull and worn paintjob or a plausible story
