Gel coat is cured when it is no longer tacky to the touch, appears even and smooth, and maintains its finish without leaving any residue on your finger. Additionally, a properly cured gel coat will be hard and solid with no soft spots or sticky areas. If unsure, you can perform a small scratch test in an inconspicuous area to check hardness.
