Bought my cruiser from a guy in Oklahoma and it must have been stuck in some heavy duty clay! I have spent days with a screwdriver, going to the car wash, more scraping, more high pressure wash... still clay all over the frame and inside the frame. Any trick to getting it off? So far I have probably gotten 10 pounds of clay (at least!) off the frame. It was even caked above the transmission and the frame rails were completely packed.
