Thanks, good to know. Ironically, my can of WD-40 is extremely low on propellent (doe anyone else hate having liquid left in a can that just wont come out?) so I could only get a few drips out, then I just rubbed it around the surfaces and threads that need to stay clean. I mostly put it on to inhibit any rust between now and when I get them in the engine. I'll keep you guys posted.
