Re Painting of the hull

[Normagain]

So, what is the deal on factory paint anyway, did they paint the sides at the factory?

My 74 red hull boat appears to be painted this way. I thought the red was gelcoat original, but looks to be thin like paint. Interestingly, acetone will not take it off for the most part but will on the transom so I think the previous owner color matched it somehow to touch up the transom with some kind of non marine paint.
