Hi,
I bought one of these:
I came to use it the other day and found that the some barely trickled out. I looked at the can of foam and it said "use by November 2011", so I thought that the foam had "gone off" or whatever foam does after it has reached its use by date. (what does happen to it?)
I bought a new can of foam but before fitting it I thought I would run some cleaner through the gun to make sure it was clear. Nothing came out the other end.
I'm now wondering if the gun is at fault rather than the foam?
Is there any DIY repair that can be made to the gun or is it just a matter of throwing it away and buying a new one?
I can't remember when I last used it. Perhaps the fact is that they are designed for regular use by tradesmen rather than occasional use by DIYers?
I think the price of the gun has doubled since I bought mine. I half wonder whether for occasional use I would be better going back to the handheld cans but expect to write off a can after each use. I suppose that would be fine except for very small jobs, where it would be a waste of a can.
What does the group think/do?
