General Finishes does not think light scratches on a door are so significant that it would be necessary for you to strip down the finish.
Instead of stripping, GF recommends that you try:
- Clean the surface and lightly scuff sand with a 220 sanding pad.
- Tone the scratched areas with a mix of 1 part General Finishes Light Brown Dye Stain and 2 parts General Finishes High Performance Topcoat Satin. 1-3 coats may be necessary to match your current color.
- After touching up the areas that are scratched, follow with 1-2 coats of the mix over the entire surface of the cabinets to even out the color and surface.
Even though topcoat is included in the mixture with Dye Stain, the surface should be sealed with several coats of stand-alone High Performance.
