I find that these small .5 ounce units are the way to go if they are priced appropriately. Every time I buy a larger tube of the stuff, it goes bad before I even get through 1/4 of the tube. This way, the next time I use it, it is either only .25 ounces wasted, or it is coming from a brand new tube, fresh and ready to go.

I first started buying this at auto stores that comes in black, red or blue colors. I am amazed this product is not more well known as it sticks to almost anything and gives a unbelievable bond.I first bought it to use on my valve cover for my old Ford escort, worked great. I then used it on the water pump (no gasket used, i just smeared this stuff around the thermostat housing) never had a leak. I noticed when it dries, it dries hard but a tad flexible. I kept having my rear view mirror fall off my windshield, after trying that exposy for it, I thought, let me try this Permaatex "Gasket maker" so I put a dab on the mirror and had it tapped to the windshield via duck tape. Day later, I removed the duck tape and that mirror has never came down since!I have this key chain that has a small deer in a glass cube, it came apart from the chain, I glued that....amazing bond!I had a small leak from my transmission hose that goes to radiator in my 99 Volvo, not a huge leak, but a constant mslal leak, smeared permatex all around the hose....all dry since then!Glass to metal, metal to metal, metal to plastic, this stuff is amazing!It's way better than super glue or any glue. It bonds great and holds strong!I use this on anything that I need to have something glued to.

If you always are using RTV black but just for little jobs at a time, these are perfect. Would always get the big packets but then when halfway done with it the RTV black would dry out and have to throw it away. this way i never dries out since it will all be used by then.great product!
