how would i weather track? i have a book that breifly mentions it. all it really tells me is to get an aresol spray can and spray the tracks, then take a track eraser and clean it off after it dries. the one thing that struck me as odd is that aren't the rails and the ties gonan bea different color? in that case should i use a micro brush and paint the sides of the rails ( so i don't have to clean the tops of the rails) and then paint the ties seperately? it might take a while, but i figure it would look better in the end. is it worth it?
