Bob Smith Industries BSI-201 Quik-Cure Epoxy - 4.5 oz. Combined, Clear - 5-Minute Fast-Setting Adhesive for Wood, Metal, Glass, Crafts & Repairs Review (2026)

How the two-part system works

Quik-Cure ships as 4.5 ounces combined between its resin and hardener bottles, which are mixed in equal parts immediately before use since epoxy begins curing as soon as the two components combine. According to the manufacturer, the mixed epoxy offers a 5 minute working time before it starts to set up, so a builder needs to have parts positioned and ready to bond before mixing rather than mixing early and working slowly. Once applied, bonded items can be handled after about 15 minutes, and the manufacturer states full strength is reached in about an hour, which is markedly faster than slow-cure epoxies that can take a full day to reach final strength.

What it bonds and where it works best

The manufacturer lists hard wood, glass and metal as the materials it bonds to best, with balsa wood, soft wood, fiberglass, ceramics, hard plastics, white foam and reinforcing materials also bonding well. This spread covers a lot of common scale modeling repair jobs, from reattaching a metal photo-etch part to fixing a cracked resin base or bonding a heavier accessory that a thin CA glue joint might not hold under its own weight. Because the cured epoxy is clear, it blends into joints on resin, clear plastic or glass without leaving an obvious dark line the way some epoxies do once fully set.

Flexibility and where not to use it

One distinguishing feature the manufacturer calls out is that Quik-Cure cures to a slightly flexible consistency rather than a fully rigid one, which is meant to help it hold up under vibration or light stress rather than cracking the way a completely rigid adhesive can. The manufacturer also states it should not be used in areas subject to long-term water immersion, though it notes the epoxy is fine for the internal structure of wood-framed boats that are not permanently submerged. Builders working on display models kept indoors are unlikely to run into this limitation, but it is worth knowing for anyone building something intended to see regular water exposure.

Working with the short cure window

The fast 5 minute working time is a double-edged trait: it means a repair or small assembly can be handled and moved on from quickly, but it also means larger, multi-part assemblies where several pieces need positioning and adjusting are rushed, since the epoxy will begin thickening before everything is placed. Builders working on bigger jobs typically either mix smaller batches in stages, work in sections, or switch to a slower-curing epoxy with a longer open time when the assembly calls for more careful positioning. Compared with a one-part cyanoacrylate glue, mixing two components in the right ratio also adds prep time to each application, even though the resulting bond is generally stronger for heavier parts.

Verdict and who should pick something else

For repairs and small to medium assemblies on wood, metal, glass or resin that need a strong, clear-curing bond fast, Quik-Cure matches our score of 8.4 out of 10, backed by its quick handling time and generous 4.5 ounce combined supply from a hobby-trusted brand. It is a weaker fit for large assemblies with multiple parts needing careful alignment, where the 5 minute working time does not leave enough room to adjust everything before the epoxy sets. Builders who need a longer open time for complex, multi-piece bonding jobs should look at a slower-curing epoxy instead, saving Quik-Cure for smaller repairs and single-joint assemblies where speed is the priority.
