900 Moldable Silicone Putty - Gray Rectangular Shape

I recently purchased a YoloTek GoPro Powerstick. That unit is supposed to come with a very small amount of their silicone rainproof putty to wrap around the wire connection on your GoPro in order to keep rain/water out. Unfortunately, they seem to be having some issues; as seen by many reviews, a lot of their Powerstick packaging doesn't in fact come with the rainproof putty like it advertises (which I believe has been proven to have been an honest mistake on their part, which they do attempt to make right with their customers once it's brought to their attention). And buying it separately is just ridiculous due to its high pricing (~$30.00 per box, last time I looked). This E/Fusing 900 here works phenomenally as a replacement. It doesn't dry up (even on a hot, Florida summer afternoon) and its consistency remains the same. It's very easy to work with and creating a functional seal around your GoPro wire connection(s) takes little effort. And, one of the best things? You get a significant amount of this stuff; more than I'll ever need for my multiple GoPro's (the photo of the roll in my hand is what was left after I used it to generously seal up one GoPro in two spots on the Powerstick). All at a price that equates to half of what YoloTek charges for a box of their rainproof putty (which they only supply a small amount compared to how much of this E/Fusing 900 that you get). This stuff has many different uses, but it has just knocked it out of the park for my purpose. The only cons that I've encountered so far: 1. If you're not familiar with how to successfully waterproof an electronic device (as opposed to making it water resistant), you can kill a GoPro or another device. Of course, this is entirely based upon the user and the E/Fusing 900 is not at fault for it. I just believe that it can give a sense of false security to those that look at it incorrectly. A great example to give you here is with my GoPro that you see in the photo that I uploaded. It's a GoPro 8 with a new battery door on it that allows for the USB power cord to be plugged in. This new battery door is not waterproof. Some are, and some aren't; mine isn't. Some users have killed their GoPro's by thinking that they've waterproofed the unit by applying the E/Fusing 900 (or in their case, the Yolotek silicone putty or something similar) like I have, which is not the case. It is simply water resistant. If submerged, water will enter the cracks of the battery door and kill the GoPro. Again, this ultimately is user error, but worth bringing to your attention if you're wanting to use it for the same purposes as I have. 2. After handling the YoloTek silicone putty that one of my friend's bought, it is easier to work with, but not by much. 3. The color might not be appealing to some people. This is where the clear YoloTek silicone putty can outshine the E/Fusing 900. I don't mind at all, personally. Especially since options appear to be so limited. Good luck with your projects, everybody!

This 900 Moldable Silicone Putty is basically Play-Doh’s serious, grown-up cousin—flexible, moldable, and ready to fix whatever you throw at it (or at least pretend to). It sticks, it seals, and it even handles heat like a champ—so you can patch up stuff without turning your house into a science experiment. Bonus: if you get bored, you can always sculpt a tiny masterpiece instead of fixing things. Multitasking! If you want a putty that’s as versatile as your questionable life choices, this one’s a solid pick.

I took off one star not because of a problem with the product itself, but rather with the fact that there were no instructions with it or online. It worked great. I needed to plug a small gap around the intake and exhaust PVC pipes for my furnace where they went through the outside of my basement wall. I couldn't use caulk on the underside of the pipes because of how close they were to the ground. It was easy to break off and roll pieces of this to the shape I wanted and them push it into place. It adhered fine. I would buy again.

I just purchased this putty for a 2nd time, which says a lot as I don't buy a product again if didn't work as expected. I used it both on PVC and electric conduit to help seal against water and it worked like a charm. It's very pliable and easy to use.

I saw this product and the description seemed so similar to Sugru, so I took a chance and purchased it. This product actually has several different formulas and the formula I purchased was not similar enough to Suhgru, so I’ll be giving this to my local handy man and hope he can use it, and I’ll go back to using my trusted Sugru for common household repairs.

This stuff is great. Like 2 part epoxy but removable and not permanent

Works great to seal around under sink plumbing!

Worked as it should

Excellent moldable putty! Used it for the water fountain and it has held up great!

good for sealing stuff but cost wise you might do better going to your local hardware store

Product works superbly for the job I have for it. It prevents leaks in my molds and I will continue to buy and use this putty.

Its fine but some issues: Not sticky So taught and doesn't get soft after playing with Not really reusable or works stand alone without a glue

Bought this product to fill the gap in the hole in bricks. It looks smaller than the image on Amazon. Glad to have found this item. makes less mess.
