Hylomar Hylosil Black RTV Silicone Sealant. This Hylomar Hylosil black RTV silicone sealant is designed to form to any shape and create a seal against any surface. This the perfect sealant for use on your Volkswagens' windows, doors, or any spot that you have developed a leak and want to close it up. Hylomar black RTV sealant is also great for making quick gaskets, or adding an extra sealant layer to a gasket.
When you are reassembling your latest Volkswagen project you should use a high quality threadlocker, like the Hylomar threadlocker shown below. If you are installing a head gasket or need a higher temperature sealant we also have the original Hylomar blue gasket dressing.
