I just finished cleaning some pre-war lithographed cars using mild soap and water and a toothbrush. The cars look as good as they are going to get considering the scratches but the finish looks dull. What do you suggest I use to get some of that shine back. I've heard of using Pledge but read that it contains silicone and shouldn't be used as you can never get it off. Can anyone make a suggestion?
Thanks for your help.
