How to do a Basic Wire Splice

I'll try to post a pic of it today for reference. I didn't even know it had a sealer inside when I bought it. After my first splice I saw this goo oozing out and of course stuck my finger in it to see what it was. It's like grease, spreads to everything you touch thereafter. Let it cool!

They also had some pinkish tinted clear butt connectors that were heat shrink with the sealer. Kind of neat. I used some in my dash wiring for splicing in my gauges.
