How do I clean this gunk!

I just got done cleaning up my manual steering box. I used the purple clean and a plastic scraper but it didn't get all of the 45 yr old gunk. Bought a can of Berrymans chemdip as that stuff used to do a fine job. Put the steering box in a plastic pan and puored the stuff on, brushing every now and then to get fresh stuff on. After a few days it had all the gunk off. Now I have to figure out how to change the lube and what kind to use.

The stuff doesn't stink near as bad as it used to, so I figured it was watered down. Had the open pan sitting in my shop on the floor soaking the box while I painted my new Mopar RB block with engineenamel (Chrystler hemi orange of course). Painted the block at noon Sat and left it sitting outside the shop door in the sun for a few hours. Returned to a nice flowed out paint job that was tacking up nicely. Tucked it inside the shop for the night (pan of now well used Berryman on the floor). Next morning the paint is starting to have a krinkle finish. Left it in the shop to further cure and the shop gets kinda hot from the sun. By that evening the paint has softened and was running in little waves. I think outgassing from the non-stinky Berryman was the culprit. We'll see if letting the block sit in an open but covered shed getting heat and sun in the afternoon will cure the paint.

Just something to consider as I have never had that happen before, but I never had a pan of non-stink Berryman sitting open around fresh enamel before either. Whoulda thunk?
