What to Compare Before Buying

- Color match: Confirm the factory color name and test a small hidden area before applying it where visible.
- Surface: Check whether the repair material is suitable for your specific surface and repair. The listed surfaces are noted below.
Compatibility, Size and Fit
In addition to fiberglass, the product description lists chip repair on carbon fiber, aluminum, PVC, acrylic, and plastic. Confirm that the intended repair and surface fall within the stated use. The above-the-waterline restriction still applies.
What Is Included
The kit includes a mixing stick and hardener. The source does not specify other included items.
Setup and Correct Use
Clean and prepare the surface, then mix and apply the kit according to its included instructions. Allow it to cure fully before sanding and polishing. Follow the instructions for the exact preparation and application details.
Before You Decide
Confirm the 1 oz size and black color, check the color match on a hidden area, and make sure the repair is above the waterline and on a listed surface.
