Nice work so far. Sometimes it's just as quick to make all the body from plasticard than trying to
chop up a good wagon that is only half right to start with.
Top class model, well done. There is nothing worse that the last stage of varnishing going wrong, but sometimes it can
help with weathering even though it was not planned.
That shade looks ok. If you give it a bit of thinned brown paint and take most of it off again it should dull it down a bit.
The longer you leave the brown on the more it will stay on.
