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.

Excellent product. Do not rip, thick and very good adherence. I wish the label would stay on the product instead of being part of the plastic wrapping. This would help for when I need it again to buy it again. :) Not sure long term - will have to update the review if needed.

Seems to be good quality tape, as advertised. I used it to repair a shaded-pole motor, where I needed to cut the existing tape in order to remove and replace a thermal fuse. The replacement tape looks and feels as good as the original. My only concern is that the tape does not feel as 'sticky' as suggested; but it is holding and working well after several days of use. For anyone interested, a "flame test" shows that the tape will burn - probably the adhesives - but the glass cloth stays in place after the flame extinguishes itself. This is well beyond the temperature spec for the tape though -

I used this tape to wrap a thermal fuse in a sandwich toaster. The fuse was rated at 290C and the tape seems to have no trouble holding up to this type of application. Good adhesion, easy to work with.
