Hi all... New guy here with a question about my frame/suspension and other random bolts. They have been painted with a brush some sort of hardened black material. My 2018 2500 was not like this. I've attached a few pics showing what I mean. Is anyone else's like this? I can't get a socket on them correctly and am worried about this messing with the threads on the bolts for future maintenance. Any info would be greatly appreciated.
