As a fellow DKoK collector, I can appreciate a good trench system
You have a fair few bubbles with the wooden trench walls, these probably could have been avoided by using an old paintbrush and painting your silicone on.
Ooohhh! and don't forget that the 10L pressure/paint pots that we all generally use, can be turned on their sides and a shelf/shelves made to keep the work level if you need more room than the base would give you.
