True statement if using Alodine 1201

If using Alodine 1001 it’s almost undetectable (will darken just a bit depending on strength of bath and exposure time).
This is what’s used on alternators and starter housings


i ordered RPM but have a couple gallons of alodine here for motorcycle stuff that i have done for customers. ill give it a try and see what happens. never thought of even trying it.
