Semco Sealant Gun

Here's my new (used) Semco sealant gun. Now this is a handy little tool! I used it to finish up the last outboard rib and it makes applying proseal a breeze, almost fun. It uses pneumatic pressure to push out the sealant in a very controlled manner with the ability to stop the flow instantly. It was much easier to encapsulate the rivet shop heads with it instead of scooping and dabbing with a popsicle stick. You do have to fill the plastic tube (goes inside the metal housing) with your sealant but that wasn't too hard. I told Paula that this would make a great cake or cookie decorating tool...just use icing instead of proseal!
