I removed some of that 40 year old brittle tar based sound deadner Ford used in 56 Ford Pickups on the back of the cab wall. It came off in sheets while other areas remain adhered to the sheetmetal and had to be scraped off with a sharp chisel. This left a tar like risidual on the sheetmetal that is very hard to remove. Gasoline helps, followed by acetone. Im getting ready to spray the panel with SPI Epoxy. I wiped everything down with a mixture of Dawn and water, rinsed, then wiped again with SPI 700. My question is by using the gasoline and acetone during the process of removing the original finish from the sheetmetal, am I in danger of an adhesion problem with the SPI epoxy, even though I did the final cleaning with SPI 700?
