Review: Perfect for Sealing Metal – Strong, Watertight Bond - I used the 3oz Marine Adhesive Sealant 5200 to seal a panel on our aluminum trailer, and it worked great. I was looking for something that would give me better adhesion than just regular silicone, and this definitely delivered. The sealant is thicker and more durable, so it felt like I was getting a permanent, watertight bond, which gave me peace of mind knowing the patch panel is securely sealed. A little goes a long way with this stuff, so you don’t need to use much. The black color blends well with the trailer, but I noticed it also comes in white, which could be useful depending on your project. While it’s on the higher end price-wise, it’s totally worth it to avoid the alternative—water intrusion is definitely not something you want to risk. Overall, I’m confident that this sealant will hold up over time, and I highly recommend it if you’re looking for a strong, long-lasting seal. It’s perfect for outdoor or marine applications where you need something tough and reliable.
Review: Seals great! - Used to seal around the skimmer of my pool. Works great!!!! It was leaking and I was able to apply even with the area wet! great product!!!!

### ⭐⭐⭐⭐ "Permanent"
*by M***Y on January 21, 2026*

The first tube I ordered came hard in the tube and would not dispense. The seller quickly sent a new one out to me. I used this for pool tile repair. White was great color for the repair and sealant cured underwater. This stuff cures rock hard and seems bullet-proof. Do yourself a favor and get the bigger tube -it's only a few bucks more.
