Well.. how far do you want to take it?
The factory paint under the hood leaves much to be desired. I don't think it was cleared over and no matter what you do it takes a ton of work and basically a motorless engine bay to get the paint decent in there. Im speaking of the strut towers and underhood area with this. How far is the engine broken down? If the motor is still all bolted up I would say a simple thing would be just a good wipedown and cleaning areas that you normally can't get to. If you want to tear it down start with the valve covers
