About this product

A gasket maker that skins in minutes and reaches full strength in 24 hours. This 2004 sheet says dry to touch within 5 minutes, while another copy of the sheet says within 15 minutes, so the touch figure varies by edition. It is a different product from the 90 minute Right Stuff already on the site.

Using this specific product

Permatex Permatex The Right Stuff Gasket Maker is listed here as the Instant gasket maker version for gasket sealing, engine assembly, and oil pans. For using this product, the useful question is not simply whether the surface looks finished—it is whether the exact next-action milestone shown above has been reached.

Before you start

  • Confirm the package says Instant gasket maker; related versions can use different timing.
  • For gasket sealing, engine assembly, and oil pans, pay particular attention to the exact variant, preparation and environmental conditions.
  • At 23°C (73°F) and 50% relative humidity.

How to check readiness

Check the real material or treated area at the slowest location before the next step. The data sheet says to assemble parts within 5 minutes while the sealant is still wet. The data sheet says it dries tack-free in 2 hours. Touch only a hidden edge first; a dry surface can conceal a soft layer underneath.

Avoid this mistake

The first visible change is not always the manufacturer’s final-use milestone.
