My DH used it to repair/rebuild an old composite bird that was on the mailbox of the house we recently bought. It worked incredibly well! Once it was repaired, he painted it. It looks great back on the mailbox.
This stuff is awesome, I use it for everything! Its the only thing that stuck the handle back on my favorite coffee mug. It lasted 10 years, I just bought this new pack to re attach the same handle (10 years later mind you so I consider that a success) and its stuck on again, and again going through the dishwasher.
This stuff works so great when fixing little holes or what not. It gets super hard when its dried! Perfect for little home improvement jobs
