I've been attempting to upgrade/improve (?) the look of some of my steam locos by adding number boards to the front of the boiler as well as painting a white edge along the walkways along the side of the boiler. I usually end up with some white paint where I don't want it and have been trying several ways to remove the excess. Until now, results have not been great - usually I end up removing part of the paint that I didn't want removed. Today I tried something new (at least it is to me). When I have finished applying the white paint to the area I wish to cover, I clean my brush with Varsol. Then keeping the brush damp with Varsol, but not soaking, I applied it to the area of the unwanted paint. If this is done immediately after applying the paint, the Varsol seems to loosen the unwanted paint. Then I cleaned the brush again with Varsol and dried it almost completely on paper towel. Next I dragged the bristles over the Varsol dampened paint and the brush soaked up the unwanted paint. Sometimes I had to repeat the process two or three times, but it seems to work. I end up with paint where I wanted it and none elsewhere. Anyone done this before or have I found a new technique? With a small brush, it is possible to work to very close tolerances. Any comments from the experts??
