Hello wonderful modellers..! I am new to the hobby and have been reading and reading and reading.. I have a question about fitting parts.. No matter how carefully I cut some parts they never fit quite right. If I try to sand the edges a little the whole thing seems to swell and not sand nicely. I have tried sealing the edges with glue to stiffen them but as soon as I sand a little the edges start swelling again. Is there something I can do to get the edges stiff enough to file without making the ink on the outside wash of? Any assistance would be greatly appreciated. I appear to be a perfectionist and want everything to fit perfectly..
