Gorilla Super Glue Gel
The go-to instant repair glue for small jobs on plastic, rubber, and metal. The gel body makes it far more controllable than watery super glues, and the impact-toughened cure holds up to knocks that would shatter a brittle CA bond.
| Type | Cyanoacrylate (CA) gel |
|---|---|
| Set time | 10-45 sec, no clamping |
| Full cure | 24 hr |
| Bonds | Most plastics, metal, rubber, wood, ceramic, leather |
| Strength | Impact-toughened; absorbs drops and shocks |
| Format | No-run gel with anti-clog metal-pin cap |
J-B Weld SteelStik Epoxy Putty Stick
A hand-mixable steel putty that patches, rebuilds, and fills holes in metal. Where a thin adhesive just runs off a gap, SteelStik packs in, sets in five minutes, and machines like metal, making it the tool for stripped threads and rusted-through repairs.
| Type | Steel-reinforced hand-mixable epoxy putty |
|---|---|
| Set time | Sets in 5 min |
| Full cure | Machinable after 60 min |
| Bonds | Steel, iron, aluminum, most metals plus wood, concrete, fiberglass |
| Strength | 4000 PSI tensile; drill/tap/grind/file/paint |
| Temp range | Up to 350F continuous, 450F intermittent |
Our verdict
These solve different problems. Reach for super glue (Gorilla Super Glue Gel) when two clean, well-fitting surfaces need to bond in seconds - a snapped plastic tab, a loose trim piece, a cracked ceramic. Reach for epoxy putty (J-B Weld SteelStik) when the repair has a gap to fill, missing material to rebuild, or a hole to plug, because you can knead it into shape and it sets like metal at 4000 PSI. Super glue is faster and invisible but only bridges hairline gaps; epoxy putty is slower to shape but structural and machinable. If the parts touch cleanly, use super glue; if there's a void, use putty.
