Glue gun issues I buy the Weldwood by the gallon, I have had this particular gallon a month. If I do switch to du grip, I clean the gun first. I was having such issues with the gun today, that I cleaned it and tried the du-grip just to see if it worked. It did. Then I cleaned it again and switched back to the weldwood and again, it wouldn't work. The strange thing is I have been using this almost daily for the last several weeks and it's been functioning ok, I would have to stop and clean it every once in a while, but the last few days its just not working. And of course, I am on a deadline, trying to wrap some plastic trim for an airplane. I have the air pressure knob on my gun too and I have tried adjusting it to no avail.
I'm pretty sure I've got gremlins. I'm always up past midnight working in my shop - the little buggers must have snuck some of my sunflower seeds.
