Rated 1.0 out of 5.0 by RanchBoss Made the job twice as hard
Used GE silicone sealant for the lid of a feed bin, took hours of prep work. After finishing I was pretty happy with my work and left it overnight. The next morning it hadn't set even a little. Apparently this is a recurring problem with GE silicone sealant.
Now I have to drill out all the rivets I used and clean up the goopy mess. An entire day wasted.

Rated 1.0 out of 5.0 by Len Directions can't be read
The directions are in such small type I can hardly be read with magnifying glass. Used life chat to find out what to use for clean-up. I was told to use soap and water. Apparently live chat operator couldn't read the directions either. Eventually discovered that mineral spirits, not water should be used. Never did figure out the safety instructions, so took my chances. Good luck.

I found this stuff a few years back and it's been in my inventory ever since! I use this stuff to seal roof penetrations for the solar collectors I install. So far I've used this stuff on over 1000 systems and haven't had a single issue with leaks! Yeah, there's less expensive products out there that could probably do the job, but this stuff gives me peace of mind knowing that I won't ever have to deal with an angry customer that has a leak in their ceiling. This stuff applies easily, dries quickly & clear and it doesn't crack or shrink and pull away from the materials it's intended to bond to. I've applied it to metal (copper, aluminum, stainless steel), PVC, wood, Trex, asphalt shingles, pipe insulation and rubber gaskets... and it has provided a water tight seal around all of them! Also, not all silicone's are the same! I tried buying another brand that was 1/2 the price and had what appeared to be all the same ingredients. That product ended up having an acidic reaction with the asphalt singles! It caused damaged wherever it came into contact with a shingle and it also ended up shrinking and pulling the surface off of the shingles allowing water to get underneath the sealant. I don't have that problem with the Silicone II. However I set the product (as a bead or smeared out) it STAYS that way.
HINT: This stuff is sticky! If you are trying to get a nice smooth surface when smearing it out, spit on your finger before smoothing! Yeah, it's kinda gross, but then it doesn't stick to your finger and you'll get a glossy smooth surface! ;-)

Rated 1.0 out of 5.0 by DrSnooz Worst sealant EVER!
I grew up using GE's Silicone II sealant. For my contractor father, uncle and grandfather, it was the goto choice for anything you didn't ever want water to get into. Period. Naturally, I bought a bunch of it when I went to reseal the windows, hatches and corner beads on my 20 year old truck camper recently. I spent several days carefully carving out the old silicone, prepping the surfaces with acetone and resealing. When I was done, I relaxed and prepared for another 20 years of trouble free service.
After a scant 3 years, I was horrified to find water pouring into my camper with each rainstorm. Upon inspection, I found that the silicone was releasing all around the windows to which I had so carefully applied it, forming long open cracks in the process. Water was pouring freely past this useless, garbage silicone. Do not use this under any circumstances!

Rated 4.0 out of 5.0 by Architecturalmillwright GE makes the best silicones
Only thing better is GE contractor brand can't buy it in stores but used it for many years when I did window replacement you can actually caulk a window in and not screw it in I did so for a temporary window install in my bathroom and almost couldn't get it out about 3 weeks later took me about 2 hrs to do so I no longer can get contractors brand so I have been relying on GE 2 can't say it is as good (not much less inferior) but you won't beat it with any other brand I have found available

Rated 5.0 out of 5.0 by NYCBK Works great
IF only I had an applicator for this product. I assumed (wrongly) that I could squeeze this out of the tube, but I think you need a caulk gun for it to work. Oops. Oversight on my part.
However, the material itself does work. I used it to adhere wood trim molding to a mirror surface and it's great to use, and easy to clean up. TIP: don't bother washing it off your hands if you get some on by accident. just wait for it to dry and then peel it off. FUN! (if you try not to harp on having chemicals on your skin)
I just used a disposable chopstick and applied this like glue. Even though I made a mess, I just used a razor blade and sliced and scraped away any mess that oozed out where it shouldn't be. Comes off easily when you want it to.

Rated 4.0 out of 5.0 by whiten Peace of Mind
Reading the label "Rainproof in 3 hours: and that it can stand extreme temps and moisture I was given peace of mind. I ended up using his on the threshold between my front porch concrete steps and the doorway. It seems to be working but won't know for sure. Unlike the previous reviewer I couldn't do a uniform caulk with tape because the cracks and gaps were irregular not to mention in hard to see areas.
I will use this again for weatherproofing my windows, backporch steps and any other gaps or cracks I can find.

Rated 1.0 out of 5.0 by Jeffm Does not dry EVER
This product will NEVER dry if used past it's date code. The problem is that the manufacture does not print the date code on the product so you can easily read it.
