evaporust on axles

[BillOhio]

Had some crude on end of a me shafts and sat the hub end in evaporust for a day. Rinsed them off and found a big blue paint dawb on the edge of the hub. Runs from one stud to the next. Evaporust is neat stuff

I cannot count how many parts we've used evapo-rust on from suspension parts to our driveshaft and everything in between. And yes, exactly how we found so many of our paint markings.
