One of my customers says he uses WD40 on the glass of his Harman Advance. He cleans it with glass cleaner, and then rubs some WD40 on after. He claims that it helps keep the glass clean longer by preventing soot and ash sticking to the glass. Does anyone have experience with this method?
Being a Harman XXV owner, I have experience with viewing glass that gets dirty pretty quickly. I would like to try this, but don't want to risk doing more harm than good.
