Cylinder Install in Minutes

I'm getting ready to put my cylinders on in the next few minutes. I'm heading to Advance Auto for some Spray on Copper Adhesive for the cylinder to block application. OMR posted something about ease when it comes to dismantling with it's use.Question my head won't be completed until the first of the week will the copper application still be good after that period of time?

I wouldnt use it until your ready to button it up. You wanna let it tack up a bit before installing.
