Hello, I recently tried to install a roof rack onto my 2012 997.2 4 GTS. However 3 of the 4 plastic screws stripped and could not be removed. I purchased replacement parts (#996 504 911 00). I found directions and almost finished popping the first roof panel plate off. Then I noticed there was some black sealant of some type that keeps the outside of the plate with a watertight seal. My question is what is this sealant? Is this flange sealant (Porsche Sealing Compound - Loctite 5900)?

Thank you!
