This inquiry is inspired by all the discussion under the "ATG" topic. MY biggest shop nuisance is the continual clogging of the tip in glue bottles. We use FrameWeld glue, which is great, but the bottle's small opening is constantly being blocked or restricted by semi-drying glue. Capping between uses does not seem to help. I tried installing a nail thru the cap, but it rusted, staining the glue. Why can't they make a glue bottle with a cap containing an inner spike which would automatically "ream out" the bottle's tip when closed? Or how about a Teflon-lined bottle nozzle? Anyone got any do-it-yourself solutions in the meantime? (I wonder what the dollar value would be of all the time spent over a year cleaning out those clogs!)
