do you use the pumps---can they be cleaned and reused---if storing for a period of time do you need to remove them and recap---are they air tight----tks.joe
I just open the gallon and pour out what I need and recap it. I store it in my basement where it's cooler. I have to warm the resin before I pour it because it thickens when cold. I've had it last 6-8 months but it gets thick and brittle when it gets old.
