Prepping and Engine for Paint

[Darinh]

I have finished rebuilding my engine and now am ready to paint it. What is the best way to clean everything prior to paint to remove any oils, pre-lubes, etc. that may have contaminated the surface during reassembly?

My case was alodined and the cylinders are new. Everything has been properly prepped to this point but I want to get rid of the oils during assembly. I have been told that a solvent such as MEK or Lacquer thinner in a spray gun works good. Any ideas?

I am a big fan. It is a Grease and Wax remover. You could spray it on I guess, but I just wipe it on with a saturated rag and then wipe it down with a clean cloth.
MEK is a very aggressive solvent. I only use it when I need it. Laquer thinner is fine, but it is pretty agressive too. Prep-All seems to be just right for this kind of job.
