Stuck on glue

As part of a jewelry project, I needed information on glues to use.  I received no response to my question on Facebook, so I went ahead and researched it myself.  It seems there is no real consensus on the best glue to use to glue acrylic resin to metal findings.  Therefore, I decided to buy several and test.  Here are the glues I chose to start with.

E600® was recommended by several sources, and trashed by just as many other sources.  Unfortunately, I could not locate it, even on Amazon.  While at Hobby Lobby, I came across E6000®, which I had heard about.  A number of people who complained about E600® recommended E6000® instead, so I decided to give it a try.  The package claims, "E6000® is a unique adhesive formulated to meet high-performance industrial requirements, making it an exceptional adhesive for any craft project. Washer/dryer safe."  Well, that washer/dryer safe thing is good to know.  The label also claims it bonds to fabric, metal, wood, glass, ceramic, and more.  This product is made in the USA.

One book on resin jewelry making specifically recommended Beacon Gem-Tac™.  The package claims, "GEM-TAC bonds embelishments to many surfaces including fabric, wood, glass, plastic, and more."  This already puts it behind E6000® because it does not mention metal and I am using metal findings.  Unlike the E6000®, the Gem-Tac™ is supposed to dry clear.&nbnsp; This product is also made in the USA.

Another book recommended Devcon® 2 Ton® epoxy.  As an epoxy, this is a 2-part system, so there is increased chance of error.  The package claims, "A clear, extremely strong, non-shrinking adhesive, specially formulated for high-clarity and good impact strength. Waterproof. Resists salt solution, unleaded gasoline, mineral spirits, oil, and anti-freeze."  The list of materials includes acrylic, china, fiberglass, metal, wood, concrete, ceramic, and glass.  This is the first of the products to list both acrylic and metal, something to keep in mind when gluing casted acrylic resin to metal jewelry findings.  This product is also made in the USA.

The last recommended glue (and I promise to in the future include the references) is Glass, Metal & More™.  The label claims, "Glass, Metal & More is a super strong glue for bonding glass, plastics, most metals, mirrors, canvas, rubber and many other hard-to-hold materials. Glass, Metal & More dries clear & flexible, and is ideal for outdoor applications, home, and marine repairs."  (The package's punctuation errors; not mine.)  Materials listed are glass, metal, mosaics, canvas, most plastic, and more.  It seems the United States still at least manufactures glues, as this product is also from the USA.

The 2 Ton® sounds like it will be the best product to use for my purpose.  However, the E6000® would be easier to use and is more readily available.  All of the products recommend sanding the surfaces before applying any glue, so I have to search my apartment for some sandpaper.  If I find it, I will proceed on to glue applications.
