I had this experience menz IP.Didn't get to it soon enough I guess and dried rock hard.Nothing worked until I tried Menz glaze.It removed the splatter with ease.
I know,I'm no help but had to share.:D
Quick thought,
How about doing demos/details with local cruise-ins/auto events,swapmeets etc.
You could hire some Hooters gals to help with the demos/details.:cheers:
