zap a gap

[pittendrigh]

Some weird guy named Sandy--who briefly sold "Sandy's Superfly" back in the mid-1980s--likes
to use PTFE Teflon tubing for dispensing ZapCA and ZapAGap

Cut the top off the bottle. Run the tubing down to the bottom of the bottle.
Caulk the tubing in place with a hot melt glue gun. Now you have what chemists call a wash bottle.
You do not tip the bottle to dispense the glue. You point the tubing at the glue-spot and squeeze.
You can watch the glue run up the tubing, so you can release pressure at the last minute, so
you can dispense a micro-pin-point drop, as needed, exactly where you want it. Or a gob too,
if that's what you want.

When you let go of the bottle, the glue is sucked back down into the bottle.
The tubing seldom clogs up. If it does clog up, it is ALWAYS at the tip. So you can snip off 1/32" of tubing,
without making a wider orifice. Works like a charm.

Where to buy (14-16 guage thin wall for ZapAGap and 28-30 guage for the even more useful ZapCA)

Super glue does have a relatively short shelf life. So it makes sense to buy small bottles, rather than big.
When model airplane shops offer CA glue (of any brand) at bargain prices, it usually means they bought a pallet of aging
stuff, near the end of its useful shelf life. UV cured "epoxies" are handy too. But they do not bond as strongly
as ZapAGap. Two-part mixed epoxies are the strongest and most durable of all.
