Review: Nice Tape - The double-seal tape with two-sided adhesive is an excellent choice for vacuum bagging in composite fabrication. Its strong adhesive properties ensure a secure and airtight seal, which is crucial for maintaining vacuum pressure throughout the process. The tape's build quality is impressive, with a durable construction that withstands the stresses of vacuum bagging without losing adhesion or integrity. It’s easy to apply and conforms well to various surfaces, making it highly reliable for composite work. Overall, it’s a must-have tool for anyone involved in vacuum bagging composites, offering both performance and durability.
Review: Good tape sealant - This worked great for installing a vent fan in my RV roof. Easy to work with hint - place the tape roll in the refrigerator prior to use, less sticky while placing the tape. Seemed durable once secured and there has been no gaps or leaks.
