I have been trying out different glues for the brass inserts in pen kits. As I said above, I use Original Gorilla Glue for most pens. Last week I tried White Gorilla Glue and Clear Gorilla Glue for brass tubes in pen inserts.
White Gorilla Glue is a polyurethane glue that foams and dries white. From my testing, I found that White Gorilla Glue was runny when compared with Original Gorilla Glue. That runny-ness caused the glue to drip from the brass tube before I could get it inserted in the blank. The regular Gorilla glue is thicker and gummier and doesn't drip. As advertised, the White Gorilla Glue cured faster than Original Gorilla Glue. It dried white, which I like. I may switch to it for pens because of the faster cure and white color, but I don't like the drippiness when applying it.
Clear Gorilla Glue is a silane-based glue. It is unlike other glues on the market. At the recommendation of a friend, I tried it on one special, challenging pen blank. It goes on clear and dries very clear. It does not foam. When dry, it has more of a rubbery feel than a "hard surface" feel. Storage is annoying: keep it cool, but keep it exposed to light.
White Gorilla Glue was the hardest to find on a local store shelf, but my local Walmart carries small bottles of Original Gorilla Glue, White Gorilla Glue and also Clear Gorilla Glue (a silane-based glue). They were the only local store I found that sells all three products.
Pay attention to the package labels: Gorilla also makes Gorilla Wood Glue, which is white, and several types of Gorilla Super Glue, which are clear. Do not confuse them with White Gorilla Glue and Clear Gorilla Glue.
I want to add that these small bottles of Gorilla glues are very expensive at $6 for 2 oz. They are "cheap" for me, because I use very small amounts for pen making. A 2 oz bottle will easily glue 75 - 100 pens, but it would not be cost effective for a panel glue-up. I buy the smallest bottles I can find because they have a relatively short shelf life.
