I stumbled onto some Dupli-Color Bumper Coating just last week at the local Habitat for Humanity Restore for $1.50 a can. The can has the front end of an '01-03 Sport on it (I know it's a Sport not a ST because the same vehicle is/was on their automotive spray cans.) On the front of the can it says "excellent adhesion", but in the directions it says their adhesion promoter CCP199 can be used to increase adhesion. I haven't used it yet, and have no plans to anytime soon. What I found happens to be gray, but I'm sure it's available in other colors.
