Hey Soyka! The best sealant to use when installing the # MA00A04301K or any other roof vent on your Sprinter is the LaSalle Bristol XTRM Universal Self-Leveling Sealant # 34427034145-1. We use this for installations as well. You will also want butyl tape so I recommend grabbing our Roof Vent Installation Kit # 344270KITW.
