Little bit at the back is hard to get off, and also it is in a rock strike zone
so VERY subject to paint chipping.
Yes I did the skirts myself. There is another thread around on this, but
basically...
1. Read colour code from your engine bay.
WRC blue is 74F.
2. Find someone who will make up spray paks of matched paint.
3. Remove skirts, sand lightly with wet/dry paper.
4. Use a plastic primer. Get it from same place that sells you the paint.
5. Use several light coats of paint.
6. Seal with clear coat.
As I mentioned, have a search around as this had been covered
more in another thread...
