@Ted S posted:What size brush? And how did you avoid getting excess paint on the wheel "treads" (surfaces that contact the rail)? Sorry for all the questions but I don't want to screw up locos that I paid several hundred dollars for, even though they aren't worth anywhere near that now.
Another option is gun blue/chemical blackener. Thats what I use. Same technique. Place the engine upside down in a cradle. Attach clip leads and hold a swab next to the rims. Takes about twenty seconds. You can use paint too. Pretty hard the do damage either way. Have some thinner handy if the paint doesn't go where you want.
