Painting and sanding grand hauler body

[Jamithan04]

Hey everyone looking at everyone's awesome looking paint jobs has me wondering. So I have a grand hauler that I just got done preping and priming. And I'm curious with all of the little raised details on the body, like the door hinges and rivets and screws etc. how and what did you guys use to do the base coat sanding and wet sanding. I noticed while I was going through scuffing it up before primer I noticed that there was a ton of spots missed due to the raised edges. If one could give me some insight on tips tricks and what the used to get to those hard to reach spots would be much appreciated
Thanks in advance everyone
