So I started off with a rubbing compound, which is a sort of sandpaper in the form of a paste. I used Farécla Profile 300, which was applied with a sanding/polishing machine. The machine gives more power when applying the rubbing compound, so you do not get a tennis elbow from the job. However, one has to be careful of not to use too much power and also remember to spray water frequently to cool the surface. Otherwise, the gelcoat can heat up too much, which will leave yellow spots on the gelcoat. One has to be especially careful in the sharp corners of the coachroof and cockpit. And yes, I learned this the hard way...
The rubbing compound works like a sandpaper, so it takes away a very small amount of the gelcoat. Therefore, one can also remove light scratches from the gelcoat. However, the treatment should not be repeated too often, so that the gelcoat is not removed excessively.

I am pleased with the outcome, since after the treatment, the twenty-two years old hull looks almost like new again.
