You may inform her that WD is for Water Dispersent so it is critical that the letters are in the right order & that the inventor (of it) tried 39 different chemical combinations before being comfortable with/& settling on the 40th try. I use it alot mainly cuz it is handy/thin/sprayable but alot of mechanics dont think very highly of it.
