Review: Strong bonding fast curing - Good product. Does the job👍🏻
Review: Brilliant Stuff - I upgraded my tortoise vivarium and after looking at reptile forums it was recommended to use this silicone sealant. It was so easy to use, creates a perfect seal, holds decorations perfectly. Only downside is that the smell is awful, took a few days for the smell to dissipate but would definitely use it again for non urgent projects.
