If the stuff is anything like the Tweek of the 1980/90’s, careful on tube pins. Tweek was conductive, and if any was dripped between pins on tube sockets, shorting could result.
@bdp24 , the bottle will not fit on tube pins.
Look at the instructions, you NEVER take the cap off the bottle to use these.
You place the sealed bottle on top of connections.
