Here our regard for wd40 is low. It is neither a penetrant, lubricant,or preservative when compared to more specialized products. Break free clp is my favorite for preservative. Test show a 5%salt water solution will not break the surface film of break free even after 200 hr of submersion. Also a good cleaner and have seen breakfree release stubborn parts as penetrant.
