Foam Inserts | Closed Cell Builders Foam | DIY

Trying to save money, so trying my hand at DIY foam inserts. £8 plus postage off an ebay seller for 10 M length of 30 mm diameter backer rod, used by builders to fill voids. It is closed cell foam so won't absorb sealant. I'm using 1 zip tie and a piece of Gorilla Tape over the join.
The long-term test will come in 4 weeks time.
