Disappearing Head Cement

[jcotrel1]

Anyone take a few months off from tying and come back to an empty bottle of head cement? Apparently this stuff evaporates. What are the tricks to avoid this?

Make sure the cap is screwed on tight. Check the seal and use a very thin coat of Vaseline. That should help fill the voids to keep an air tight seal. You can also place a marble in the jar to remove as much air space as possible. Air is the enemy. You can also place the head cement on a zip lock bag and remove as much air as possible before zipping close.

I turn my bottle of thinned Sally Hansens upside down (making sure the cap's on tight!); seems to work.

Put a rubber band on the bottle to make the cap as air tight as possible, otherwise bag it.

Add thinner

This has worked for me. Just remember to put the cap back on. Also has a built in "bodkin" of sorts: http://www.basspro.com/Fly-Head-Ceme...SELL_THUMBNAIL

Ever since Flexament went from glass bottles with a lid and insert seal, to a low slung plastic bottle with a cap and paper seal. I've had to quadruple the frequency of adding thinner to it, to keep it at the viscosity I prefer.

In this case, it's product packaging that's the cause.

What I use on my head cement jars, the square ones with the metal screw-on cap, is replace the metal cap with a Heinz ketchup cap. It is the one with the flip-up top and the small hole to squeeze out the ketchup. It will thread on the jar perfectly and you only have to flip up the cap and insert your bodkin through the small hole that is already there. Depending on the diameter of your bodkin, you may need to enlarge the small hole. I use Sally Hansons and just add to the bottle as needed. It seems to seal pretty good for me. Just a thought......
