Cobra Hardener – Lock It In

Cobra Hardener is the essential activator that brings our Cobra Bedliner coatings to life.
For serious durability and long-lasting performance, always mix at a ratio of 3 parts Bedliner to 1 part Hardener before application.


Why You Need It:

  • Activates curing and hardening of Cobra Bedliner

  • Ensures maximum adhesion, strength, and resistance

  • Suitable for use with all Cobra DIY and Pro Bedliner products

  • Compatible with spray, brush, or roll-on applications

⚠️ Mixing Ratio:
3:1 – 3 parts Bedliner: 1 part Hardener
Measure carefully for best results.


⚠️ Important Usage Warning

This is a permanent coating once cured. Do not apply to any surface unless you’re confident in how it works.
If you’re unsure, always test first on a scrap or disposable surface.

  • Not suitable for removal once applied

  • Misuse can result in unwanted bonding or surface damage

  • When in doubt, test it out!
