I've painted the wheelhouse inside and out. It's taken a lot of effort to get to the finish in the photos below, lots of rubbing down and repainting as I've struggled to get a decent finish. As it is it still needs flatting down and then polishing back up with rubbing compound and then polish.
I've also painted some of the smaller components...
There's an issue with the hull paint too! I painted it with Halfords Gloss Appliance White and left it several weeks to dry. But, and it's a big but, the stand is marking the hull. I've tried mouse map as recommended by Model Slipway, masking tape on top of the mouse mat and felt. The felt is better then the others but still leaving marks. I'm now thinking of a stand redesign to spread the boat's weight over the stand better in the hope that will work!
