This glass cloth tape is exactly what was needed for a project with high heat requirements. The adhesive is very strong, and the fiberglass backing provides excellent durability and resistance to tearing. It held up perfectly under high temperatures without cracking, and the adhesion remained solid. This tape is a great choice for electrical work in engines, around heat sources, or for other applications where regular electrical tape would fail.
