Painting finished engine and transmission

[makoshark]

Thanks MYWAY for the reply. The paint on the engine now is a 2 part urethane enamel. I'm wanting to change the color with HOK paints and they specifically state not to paint over metals cleaned with any type of acid based products, such as paint stripper. I realize I have a job on my hands, but was hoping for some insight on the best method for realizing my goal with this.

I do have a sandblaster and 200#'s of glass bead on hand
