Here's my first real shot at weathering a whole train, 12 cars and two diesels in all...and considering this is Nscale, please give me some honest feedback. I'm rying to get them to look used, some grimey'r than others. The basic technique was to clean with iso-alcohol, spray paint on flat primer and let dry, then apply a coat of burnt umber/alcohol mixture and wipe in a downward motion off. The wheels (mostly all metal as these are +25 year old Bachmann's) are metal and were painted in a rusty mixture I blended for some of the track. It wouldn't quite stay applied as I would have liked - the wheels being almost too slippery to hold the paint. But please - be blunt and honest - I can take it. I'm looking to improve, and your opinion will matter! Thanks.
