I removed all the bodywork from my F4i to cleanup after my spill. I've got some oil soaked into the foam backing on one of my fairings. Washing in the deepsink w/ "grease cutting" dish detergent and squegee-ing didn't get much out. I still have to Plastic Weld a few cracks, and my mechanic is coming over tomorrow. My version of trial and error hasn't worked too well. Anyone have any suggestions that they've gotten results from?
