I've read about POR15 for under the truck, but not to much on the rear axle and diff. I've removed 46 years of grease of grime and the control arms, trcking arm, springs, shocks and mounting plates...ready to re-assemble after blasting and power coating. I plan to use POR15 on those under parts I could not remove. The axle is different and not referenced for that application. Appreciate any advice. Not an off-frame repair.
Thanks
