Don---thats a beautifull thing!!! Isn't it amazing how you can go over something like that with a magnifying glass, and find no imperfections---but as soon as you get some primer on---WHAMO!!! there they are, lurking---demanding a bit more spot putty. I think that everything I painted in the last 30 years ended up getting primed about 6 times. Eventually, you either get it perfect, or else give up and finish paint it anyways.
