Crankset rust removal

I am getting very close to building the bike back up. First I need to remove the rust from my crankset.

Here are the products I used. I imported a 25 liter container of Evapo-Rust from Ireland, and tiped about 5 liters into the bucket shown. The crankset went into the bucket overnight.

The next morning I removed the crankset and it looked pretty black and ugly. I then dried it off with a rag and doused it in WD40. I then scrubbed the wet-with-WD40 crankset with 00 grade steal wool, and it came out looking pretty good. Then I painted on Rustol to hopefully prevent rust from reforming.

Here is a closeup where you can see the pitting, but at least the rust is gone.
