Permatex 80050 Clear RTV Silicone Adhesive Sealant, 3 oz

Glue works well. I used this on several little projects and it holds good

This stuff works very well and has great adhesion.

Works great and it’s multiuse too

Purchased for outdoor use. It works for a variety of connections and seals which did work, but it began to leak after one year when I used it to plug a leak on the inside of a HDPE rainbarrel. There we no way to apply on the inside when the barrel was full, and when 500 pounds of water got inside, the crack widened and, eventually, the RTV began to allow seepage. Not a catastrphic failure, but not a complete success. At least with the seal on the inside, the water pressure pushed the RTV into the crack, so it lasted for a year (looking on the bright side)

Why do I buy Permatex Clear RTV Adhesive/sealant? The only reason is that it comes in smaller handier tubes. Here is my reasoning... "RTV" stands for "Room Temperature Vulcanizing". People don't realize it, but all silicone adhesive/sealants that you purchase at hardware and auto parts stores are "RTV's", no matter if they say it on the label or not. (There are also specialized curing silicone's, such as the ones used in hobby and manufacturing mold making, but a two part mixable silicone is typically used rather than RTV.) Silicone Sealant is the best sealant available for most applications. It is far more resistant to drying out and cracking than latex based sealants, is more waterproof, and is more permanent. I personally like it because it doesn't seem to attract dust and dirt as much as latex sealants. When you absolutely need a waterproof seal (boats, engine cooling systems, etc.) you use silicone. Disadvantages to silicone is it has a very strong vinegar smell while curing, it is not water soluble so it's harder to clean up, and paint doesn't stick to it as well as latex. If you are sealing around something that doesn't see a lot of heat extremes and moisture, and/or needs to be painted, you may prefer latex. Because it isn't very paint-able, silicone is available in several colors. Silicone can have different formulations that change it's characteristics slightly. All silicone's are highly waterproof, but some formulations are even better for 100% water immersion (like on a boat hull). Some have a wider temperature range. Some dry slightly faster, etc. Permatex makes other more specialized formulations which are top notch (mostly for automotive applications), but this particular package is just great plain old clear silicone sealant. Which is better for emergencies, latex or silicone? Let's say your working in a restaurant, and you have a customer restroom sink bowl start leaking that stays wet almost 24/7. You can't close the bathroom for an extended period of time because of constant use. Do you use latex or silicone? I have been in this situation and at first chose latex because of its faster drying time. The problem was, because latex is water soluble and it was exposed to dampness constantly, it never dried, and eventually just washed off. When I switched to silicone, it was waterproof even when not fully cured. Although exposed to the damp environment it did eventually cure, all the while stopping the leak. So would I choose Permatex Clear RTV adhesive/sealant over other brands of plain clear silicone? Probably not, but it does come in that nice conveniently small tube and it is available just about everywhere. Recommended

This stuff works SO well!

Good for sealing headlights at the seam

Not much to say. It's a clear silicone sealant/gel in a tube. You squeeze it where you want it; you smooth out/wipe off the excess; it smells like vinegar for a while and cures at room temperature (RTV = Room Temperature Vulcanizing) to a clear, rubbery, waterproof finish. Like any other silicone sealant (not to be confused with "siliconized" acrylic), it won't take paint, so pick a color that's close to what you're working on. Clear works in most situations. I don't bother with the cap after I open the tube. I leave the nozzle in place and thread a tight-fitting screw into the nozzle hole. It doesn't dry out; I don't have to clean out the nozzle each time and there's no waste.

Works well, strong hold.

It would be nice if it came with a scrapper to clean the nozzle for future use.
