Hi Desp,

Been there. Done that.

We found the best way to keep the foam gun functional was:

1) Keep the can on the gun. Only change it when it's empty and you need to load a new cannister. Taking the foam cannister off to clean the gun always ended up with either the gun jamming or the valve failing.

2) Buy a tin of acetone from the builders' merchants. We bought 5l. It will last a couple of lifetimes. One of the ladies in the house had a tallish, narrow bottle that used to hold something smelly. We put some acetone in it and left the business end of the spray gun in it overnight. In the morning, it was child's play to remove the foam ready for another day's squirting.

Thanks Richard, I'll try that, I have some Acetone left from a big fibreglass resin job we did a while back. I don't use a lot of foam, usually try to use the whole can in one go, but I'm hopeless for keeping all sorts of leftover for a rainy day, can't get in the garage any more now.

I will try and enter up our 2011 energy data soon, another long meaningless chart for you...................yawn.
