Feb 2005 C/O oldcarfart.... In a 5 gallon bucket mix 1 gallon simple green or greased lightening with a large bottle of Dawn dishwashing detergent, add 3 gallons hot water & mix well. Using a pump sprayer start at one end and work backwards, leave it sit 15-30 minutes, then pressure wash it starting from the end you finshed with (this way only clean schitt drips on you ), anything that is still attached is good enough to undercoat over.
