900 Moldable Silicone Putty - Grey

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!

Love this stuff. I live in a very drafty high-rise condo on the 14th floor. You could feel the draft on the outside walls where the baseboard meets the wood floor. I put this stuff in the gap on all outside walls where the wood floor met the baseboard. Some areas the gap was so big it took multiple applications to fill the space. Afterward, you could really feel the difference. I also put it around the PTAC units in every room. I wish it had come in white as my baseboards are white, but the gray is very pale and you hardly notice it. It is also easily removable if you decide you don't like it.

This is a great product but it's expensive. I needed a small amount for a crack on a plastic shelf in my small fridge's freezer. It worked great, Been holding well without letting moisture getting in and ruining the inner lining. If they offered smaller sizes I would've bought that. It definitely work in freezer temperatures for inquiring minds.

I had to remove a front metal panel to access my air conditioning evaporator on top of my heater. (The coils needed defrosting). All went well, but I had trouble replacing the panel. It would not go into its slot, and the screw holes would not line up. After careful analysis, I realized that I had to completely remove the old putty, reinstall the panel, and and then seal where the pipes came out with new putty. The old putty was still soft, but not very malleable. The E/FUSING 900 Moldable Silicone Putty was very easy to work with, and sealed perfectly. It saved me the cost of a service call. It is clean to work with -- not oily, not smudgy, non-staining, and just the right amount of malleability. I expect it to retain its shape and seal forever. In the photo, the black putty is the E900. The gray putty is the original putty from when the heater and A/C was installed. I WOULD LIKE TO SHARE A LESSON LEARNED: Change your heater-A/C filter frequently enough so that it does not become clogged. Otherwise you can end up with a block of ice around your evaporator coils, reduced flow of cold air, blocked and overflowing condensate drainage and insufficient air conditioning.

Very easy to use & gets the job done.

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.

First time buyer and this putty is great. I make simple molds as a proto mold then I can use it again and again. Definitely recommend!

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.

Product is way too overpriced for the size of product you actually get. Super disappointed.

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

Funciona bien

I needed this to seal a couple of spots in my RV, where water was finding its way through the driver's door window seals. It's very easy to apply and to mould. After a few rain storms, the leaks were finally confirmed gone. Recommended stuff.

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