Buying rubber duck — what matters
The honest way to judge Promac Rubber Duck Liquid Rubber 5L (Red) – Flexible Waterproof Coating is against the job it has to do, not against the cheapest thing that shares its name.
- Specification over price. Two products in rubber duck can share a description and be built to very different standards. Check the spec table above before comparing prices.

- Lead time. Stock position moves weekly. We confirm availability before you commit, not after.
- Volume pricing. The listed R350 is the single-unit rate; ask for a contract rate on quantity.
