Just started the slow process of spray painting my track with Floquil Roof Brown. Since the layout is in a bedroom, and my wife thinks the smell is too bad, I am limited to doing small sections when she is not home and the bedroom windows can be opened for ventilation. I was going to move the layout outside, but it's been raining so much it's hard to plan a good day to do it without wind of course. Also the bugs would probably get in the way a little. Hand-painting the track with water based paint would have minimized the in-house problem, but I think spray painting does a much better job. Anyway, I think painting the rails really makes them look a lot better. I make three passes with the spray can; low angle on one side, low angle the other side, and straight down. Wiping the top of the rails right after spraying makes rail cleanup go much faster. I'll hand paint some black and other colors later, mostly between the rails. Do you guys paint your track before putting down ballast?
