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.

Perfect for Sealing Bulkhead
Easy to apply and good consistency - it does take a while to go off, which is nice as it leaves plenty of time to go over and neaten up with a damp rag. I was skeptical of using black sealant on a white/grey boat, but it does add a nice contrast as long as you are neat.

Great for home projects
I have used a lot of this for projects at home. It’s waterproof, but not the best I’ve used. It has a strong hold and is flexible. It’s cheap for what you get.

10/10 would buy again.
I brought this product to seal our wooden vivarium in preparation for getting a leopard gecko in there and the smell is strong but diminishes after 48 hrs with good air flow in the room it’s used in, easy to use pop cut the nossel in desired angle pop it in the gun and off you go it dries quickly and is animal safe once 💯 cured.

Great value
I used this silicone to repair an aquarium, very easy to use. Followed the instructions on the tube and once fully cured I filled the aquarium back up. It has been up and running for weeks now and the silicone has been spot on.
