activator by the quart because it has a limited shelf life. >>
Epoxy primer activator has a long shelf life.
Urethane topcoat activator will start deactivating when the cap is off and
moisture--humidity-- gets in. Screw cap on as soon as you are done pouring a
batch. As it goes bad it gets thicker. Have spare sealed can ready next
time in case partial can pours like honey. Wipe drips from screw threads as
dried uerthane activator glues cap down tight. Remember this
stuff--isocyanate-- is highly toxic and is absorbed thru skin. Use nitrile
gloves and respirator.
