It adheres well, dries fairly quickly, and is hardly noticeable.
Marc J
You can use it as weather stripping around your windows, or like a rubber stopper to keep a door from rattling.
Yellowwolf
I still have over half the tube, but if it hardens before I need it again, not much is lost.

I have found RTV silicone sealant to be an indispensable handy helper with many uses around the house, car, boat, and workshop.

Silicone is a very good adhesive for the right applications, and can be used as a substitute for grommets, rubber cushions, weatherstripping, anti-skid feet, etc. As an adhesive, I have found nothing better than silicone for attaching items to glass. For instance, as a member of a volunteer fire department, I fastened some LED strobe lights to the back window of my truck with it, and they have been out in the weather for 2 years with no inclination of falling off (although you can easily slice through it with a razor blade when you want it to come off). I also have used it inside the truck to glue small electronic devices to the dashboard, console, windows, etc. where I wanted to avoid drilling holes, and it is much more versatile than double-sided tape, except that you have to wait for it to set. For projects like this, it is good to use masking tape to keep it off any surfaces you don't want to get it on, and also to tape the object in place to keep it still until this product dries.

I have used RTV silicone to repair leaks and cracks in rubber hoses. I've used it to patch holes in speaker cones and to insulate electrical plugs. I have even used it to fix cracked roof shingles and leaky gutters. I always keep a tube of white and one of clear silicone on hand too, because whatever color it is coming out of the tube is the color it will be forever...it cannot be painted!

RTV silicone has a shelf life, and I always try to use up any open tube within six months to avoid problems. If you have a tube and don't know how old it is or if it's still usable, test it by squeezing out a dab onto a piece of paper.

This silicone did both jobs I needed done [help adhere replacement side mirror; repair damaged antenna mount] on my Sable, but it was fluid enough to get all over my hands when I had to move it into place around the antenna and in the gap between the car body and the cracked mount. I'd taped around the mount location so that wasn't too messy, but I had to use lots of paper towels before I went in the house and washed up.
It is primarily for sealing gaskets, but adapted well for these jobs. I still have over half the tube, but if it hardens before I need it again, not much is lost.

If you need to seal it, stick it, or dampen it, Permatex Silicone Adhesive is the only choice! You can use it as weather stripping around your windows, or like a rubber stopper to keep a door from rattling. I have even used it on upholstery to keep it from fraying were fabric was missing.

Good product line but I would recommend you use the clear version "Permatex 80050" by the same company and not the black one unless you really need it for some aesthetic reason.

I got one of each and the black one is much more runny and difficult to work with and seems to take longer to dry/cure. It also stinks a lot more and will stain black anything it touches - tools, hands, clothes, work area, etc.

They are pretty much the same price, definitely go with the clear one to make your project and cleanup much easier.

I purchased this to repair a small section of my convertible top that was starting to tear. So far, it is working great and blends in nicely. I've also found other uses for this adhesive and it has come through with flying colors. Every do-it-yourself-er should keep a tube close by.

This stuff sticks and works well. The only downside is that its hard to remove from you hands. Best to use clear, thin gloves when applying.

This is what you need to patch up electrical repairs on automobiles or any low voltage application. Waterproof and easy to apply.

Size Name: 3 Ounce Tube
I am a mechanic and have purchased this item and many other similar types of permatex silicone tubes. The caps on each and every one of these items have invariably split before most the contents could be consumed leading to premature solidification of the remainder of the product. THIS LEADS ME TO STRONGLY SUSPECT THAT PERMATEX IS INTENTIONALLY DESIGNING THEIR CAPS TO FAIL IN ORDER TO BOOST PROFITS BY FORCING THEIR CUSTOMERS (YOU) TO REPEATEDLY BUY YET ANOTHER TUBE OF THEIR FAULTY PRODUCT. This “design flaw” surely has lead to millions in additional profits for Permatex.

If you have fell victim of the Permatex faulty Caps I urge you to:

1. Keep all faulty caps (even if you have tried to repair it)
2. Keep your receipt of purchase
3. Submit a complaint to your State’s Attorney General (google; [your state] attorney general)
4. Submit a complaint to the Federal Trade Commission (FTC) at:
