the fuel tank hose cover of the late MY Porsche 944 is attached using nuts/studs but also a thick line of black sealant, which my best intuitions tell me is silicone, like the “Ultra Black” in the FLAPS. When the cover is removed, black sealant sticks to both the painted sheet metal of the interior of the car, and also the black metal cover. Would like to hear some ideas how to remove it. My current plan is to just leave it alone and add fresh during reassembly.
Here’s what I have tried to remove the sealant - which is partially melted from fuel vapor : a plastic scraper, blue paper towel, plastic brushes and Goof-Off. I have tried pouring a deep (~1/2 inch) volume of Goof-Off in a waste pan and dunking small portions of the cover and scrubbing it, with some progress. Apparently, no paint comes off this way. However, Goof-Off removes paint from the mating surface for the cover that is on the car. Both the cover and the car have unusual surfaces, so a brush becomes necessary. BTW there is a “packing cord” which is also listed in the parts diagram, however I did not obtain this, and it appears from removal to be a thin thread, which I do not understand how to use anyways.
