![isobond-1500x1500](https://www.rhsboating.com.au/images/com_hikashop/upload/isobond-1500x1500.jpg) Add Isobond self-amalgamating tape to your boat maintenance supplies. This self-bonding rubber tape is listed for selected sealing and electrical insulation applications, including temporary hose repairs where appropriate. Compare roll dimensions and product specifications before choosing. Follow the application instructions and treat emergency repairs as part of a maintenance response rather than a substitute for replacing damaged components. Explore the Isobond listings at RHS Boating & Marine for product details and available options.
