Angle grinder...die grinder? What do I need?

[JohnKimble]

I'm looking to start stripping the paint on my truck and was planning on picking up a 4 1/2" angle grinder and some clean and strip discs. I'm not sure if an angle grinder is my best option, or if a pneumatic die grinder or disc sander would work just as well.

I really don't know a lot about any of the above, I just started to debate getting a pneumatic tool as I just got a 60 gallon compressor. Do die grinders take specific bits or will discs made for an angle grinder work in a die grinder?
