[QUOTE=EXT2Rob;12297607]You mean as a "non-stick film" ? Sure, it won't hurt the plastic. WD40, is also used to clean and shine, as well as a "tire sauce".[/QUOTE

Yes as a nonstick surface WD40 evaporates not like silicon that drys to allow a Nonstick surface as a cooking spray. but I fear a cooking spray might gunk things up. You may not experience it But I spray the snow blower interior with Silicon so the snow won't stick Cooking spray gets washed off. by the friction of the snow.
