Air powered glue gun

Now here's a REAL glue gun. Since System Three discontinued the polyuerethane glue that I was using to edge glue my corecell foam, I switched to a thixotropic epoxy glue called "Gel Magic". It's much harder than foaming polyurethane glues and will no doubt require more effort to fare smooth.

Although this product is also available packaged into caulking tubes, I wasn't pleased with the value given that most of the tube is empty space used for the two to one mixing. The guys at Fiberglass supply loaned me a phnumatic glue gun that allows me to bulk load tubes with the product and despense it through mixing tips onto the edges of my corecell strips. It beats mixing the gue up in cups and spreading it on with a butter knife.

The foaming polyurethane glue is much easier to use but I wasn't convienced that it was stronger than the foam itself so I will have to pay the penalty of difficult sanding to come.
