That should work.
Beware: Spraying WD40 on steel or aluminum surfaces *promotes* rust. WD40 is a water dispersal developed for the navy ... the name comes from "water dispersal formulation #40". As such, it is hygroscopic: it's designed to suck up water, and is used to wash down marine fittings to get the salt water off them, preparatory to painting and other protectants being applied. If you spray down a steel tube with it and leave it sit, it will suck up humidity from the air and put that water into proximity with the metal surface, promoting oxidation. You're supposed to use WD40 to wash away grease and water (wash the crud off stuff) then you spray a sticky, NON-hygroscopic sealant on the surface to keep moisture and oxygen away from it.
