Okay… This may sound a little stupid. I am expierienced in building scenery and model kits, but have never tried weathering any of my finished work. So the other day I tried weathering my santa fe GP-38. I got black paint all over the wheels (trucks). Now when I run my loco it will run smoothly for two, inches pause for a couple of seconds, and run another two inches before pausing again. I am looking for advice on how to fix this problem and also on how to weather without ruining any functional products.
take the shell and the plastic wheel cover things off then paint them seperatley and while they are drying sprinkle some pastel dust onto them. taking them off before hand stops it getting into the moving parts
hope this helps
Just a guess, but you may have accidentally sprayed the backs of the wheels or the wheel treads themselves. Many diesels have a pick-up contact that rubs the backs of the wheels, so any overspray may partialy insulate the contact. I’ve done this more times than I can count. Check carefully for any overspray, then clean it off with thinner, 91% isopropyl alcohol or Goo-Gone. You may have to take the trucks apart to get everything, but it shouldn’t be too hard to get your GP-38 back on the roster. When I spray trucks, I’ll make a suitable mask from a slip of paper to control overspray, but I still have to clean wheel treads by hand.
