I found a way to polish off rust pits from the tapered surface of the the tie rod ends.
The (worn out) Rollock sanding cup I had not yet thrown out worked just fine, it ground through the pitting in just a few seconds. The difficult part of rust removal was the center caps. A Dremel cut off wheel and sanding discs took that off but took a while to smooth the surface up.
After sealing off the joint innards using a 5/8" Flat washer & RTV, glass bead blast, Phosphate & Oil finished and then polished flat machine surfaces again with the Dremel sanding disc and finally cut a red scotchbright pad the diameter of the Rollock disc to polish the tapered surface again. A little more burnishing the center cap to lighten the color and coated with a Rust inhibitor. Finally, re-pack with grease and install the new boot.
