New to me truck - will the paint polish?

[IT Cowboy]

I purchased a truck yesterday and the paint is a bit shiny but it isn't glossy or super smooth and it has a very slight orange peel to it. I think it is single stage as some suggested as it was re-painted 10 years ago and it looks like they never polished it fully. I am going to try to find a out of the way spot on it to test to see if it will polish. I will probably use Maguires light polish and then put a good sealant over it if it comes out nice.

Any suggestions how to test or approach this or what to do? Edit: I have to RO polishers in different sizes. I am also wondering if I need to wet sand it first with 2k grit?

Link to pic, I cannot post? If you click on it to add the + and go full size you can see the orange peel on it
