This is a Big Double Tube of "J-B Weld Reinforced Epoxy" I only need it a small quantity to Bond a small Leg to a Copper Lamp, somehow it broke apart. I followed the Instructions on the Box exactly as Described, I used a small Disposable Paper Plate and a Thin Wooden Skewer to mix both ingredients, I had no Plastic Utensils, it was easy to do and with No Fumes. I let the Lamp dry over 15 Hours, until next day, and when I checked the Leg on the Lamp was as Good as New. "J-B Weld Reinforced Epoxy" made a very Clean and Strong Bonding Fusing together the Copper Leg into the Lamp, in fact since there are four of them, I have to look for the one that was broken and sometimes its Hard to See, now I have to Find other Metal Items in need of Repairs "J-B Weld Reinforced Epoxy" did a Great Job on my Lamp!...Thank You D.D.
