Although the decision to keep it pink was a year old, so was Adam's reply that there would be a DS with less/different dye that will not stain, so...did this ever come out?
The DS I have now will, and has, permanently stained my painted garage floor from over-splash during a refill. If a formulation can be made that totally eliminates staining whilst maintaining the pink hue, then I'm all for it. However, if the new formulation still stains in the slightest, then I vote for clear spray in a pink bottle to maintain Adam's brand image.
I find it quite odd how far people will go to prevent swirling and marring their paint but are perfectly amenable to an attribute of a product that adds no functional value yet has been proven to stain paint under certain conditions; so much so that polishing was necessary to remove it.
