Quick question: In my Mitsubishi Lancer 1 of the 4 bolts (I need to have the other 3 checked) of the front crossmember had rusted to the point it broke in half. The head has no signs of corrosion. Only the part that was in the chassis has corroded. I bought a new one (not OE but of exactly the same strength) and I'm thinking what can I use to prevent the new one from rusting. Grease of course offers protection, but is it OK to be used with bolts? I'm asking because I'm not sure if any kind of lubricant would be indicated for safety reasons. Do threadlockers as Loctite offer any protection against corrosion>? Any other alternatives? Thanks in advance!
