A couple of paint questions?

[suburban99]

I will soon be painting my 1972 K10. I finally got the LS running well and its time for a paint job. The existing box has no rust but it has been massaged so many times it oil-cans going down the road. I picked up a cheyenne box with the toolbox in the side last winter.. The toolbox door was missing but with the help of a few members here I got it all rebuilt. I also have new door sills and fenders from Frank in Olympia. Anyway I want to do a single stage urethane, but I don't want it to be too shiny. I am keeping the factory colour as it gets lot's of comments. What do I tell the paint guy or girl? I don't really want the truck flat but just don't want it shiny.
