The sealant used on my TC11 is black butyl, which is readily available at most hardware stores in the roofing supply section. It's usually sold in 2" wide rolls, allowing for easy customization of shapes. You can easily form it into any shape, and pieces can be stuck together to create the desired width.
Cleaning the sealant is a breeze with Goo Gone cleaner, which should not harm your paint. This product is specifically designed to remove substances like the sealant without causing damage.
