I would like to ask how you stop the damn stuff dripping from the drain holes in the door?
Its a great way of preventing rust but the drips on my side skirts are doing my head in!!
Let it drip. WD40 won't hurt the paint. When it's done dripping, just wash the areas that it ran down on, it'll make you feel better. I drove for over a week looking like I had a major gas stain below the filler door, it was just the WD40, where it had seeped out...nothing to worry about.
