Hi Stew

I have used washing soda in the past with power supply to derust parts works pretty good.

But using washing soda hot at a higher concentration does a pretty good job of softening multilayer of paint and clearing some of the rust. Was reminded this morning that if you let paint on a part cool off and dry out the paint gets surprisingly hard again.

Really should do some controlled experiments to see what concentrations, at what temperature work best. But that will have to wait until I have the HUP back together. Right now my priority is to gets those last bits that I didn't clean when disassembling cleaned and repainted so they can go back on the truck.

Cheers Phil
