Endurance Wall Protector, previously known as Arbortone, was developed many years ago especially for cedar, in Australia, where the similar harsh U.V. to NZ, meant a better option was required. Depending on the level of exposure, and how well the coating is appiled the first time, you can expect anything from 3 - 8 years of performance before any re-coating is required. Arbortone brings the warm tones out in Cedar, similar to when the naked timber is wet.
