I just took it off the passenger side b/c I'm painting the trim (previous owner painted all trim body color:notnice: ). There was alot of black gunk that I cleaned off with mineral spirits and also 3 or 4 clips. What is the black stuff and do I need it or something like it to reattach the roofrail?
