I've been reading a ton on this and cant really make up my mind on steps for final cleaning my engine block. I'd don't mind being thorough, but I hoping for some feedback on the process.

1) The block has already been hot tanked, and Ive seen others build a DIY version out of a trash can or 55 gallon drum. Is this overkill? I also have a pressure washer with soap attachment. I'd be good with doing both as well.

2) The coolant passages are a bit rusty and the handle bars could use a good wire brushing. Should I go ahead and use electrolysis on the block? I pretty much have everything minus the borax.

3) Before pressure washing/hot tanking, I was planning on running wire brushes through all oil galleys + brake cleaner and running a thread chaser through every bolt hole.

4) During cleaning, I'm planning on using Dawn and I have sets of nylon brushes for cylinder walls, oil passages, etc.

5) After cleaning, I plan on going the ATF route on the cylinder walls and all machined surfaces.

6) When should I paint the block? Before/after cleaning? One reference had after cleaning + torching the block to continue to dry it out completely, followed by a final wipe down to remove any residual oil. Painting was done by hand.

Does this order make sense and should I skip/perform additional steps?
