I've used Plastic Padding gelcoat filler and the results are excellent. As mentioned, it only takes a small amount of the curing agent to start the reaction. Sets in around 20 minutes. Remove any excess filler around the scratches. Deeper scratches - you can leave a little proud, and then sand back. Can be sanded down with 3M wet and dry sandpaper moving to 1200 or 1500 grit. To finish (for professional results) use a specialist rubbing compound applied with a rotary polisher.
