How many times have you bought a tube of RTV to use it, then cap it and leave it in a drawer for 2 weeks to 2 months before you need it again.. The pain, The heartache, when you uncap it again to find a Plug has formed…. You have to dig it out, puncture it again or poke a hole in the bottom of the tube to use it out the butt of the tube.
Room Temperature Vulcanization (RTV) Has to Air Cure....
Well I decided to try an experiment.
I needed about 2 squirts out of my new tube.
When I got finished I pushed the remaining air out of the tube. (KEY)
Taking a 2X2 Piece of tin foil I placed that square over the tube end and Pushed it around the top to form a better seal Getting it flat over the hole is key.
Screw the cap on over the foil and tighten it (do not break the cap.)
Then fold the rest of the foil over the cap.
I had used this tube about 3 weeks ago when I decided to try this.
When I took the cap off, the foil was cut into a Circular seal over the tube and the RTV was still Fresh and came out of the tube like it was freshly opened.
Yes I had to "puncture" or dig the new seal out, but not waisting any was a wondrous thing….
