I have a layout with outdoor storage and at one time I let the sun get to some athearn and rivarossi passenger cars and now I have a half dozeh ruined roofs. I have researched lots of articles on modifying passenger cars but nothing difinitive about where I can find new roofs to replace these ruined roofs or some difinitive articles which help me with my dilemma. Need help!
Have you considered replacements for parts?
