I'm in the middle of a front end rebuild that has become far bigger than I'd intended. One result is i now have the steering knuckle out - only way to get the #@!#$! ball joint out - and have wire wheeled off 15 years of new England rust. Hate to see it immediately succomb to the rust monster again. Is there any reasonable way to slow or prevent the return of the rust on the knuckle? Some sort of coating or wax? I appreciate any thoughts!
