Reply to "Removing or smoothing dents in the tops of tinplate boxcars. Any good processes?"

Hey Guys,

I have several 6 inch Marx box cars which still have pretty nice paint jobs, but have two or three unsightly pressure dents in the tops of the cars.    I know from experience that you can never really  remove an imprint dent 100%, but I was wondering if there are any techniques to smooth them out to a more acceptable look.

I was thinking of opening up the car, and using a large carriage bolt, with a smooth round head, as a tool to gently hand-press the dents out from underneath the roofs, by rubbing the bolt head on the underside of the dent.

Any other ideas would be greatly appreciated.

Thanks, Mannyrock

P.S.-  Anybody ever just give up on removing dents, and instead use Bondo to fill them in, and then sand and repaint the top of the car?

Very timely question, as I am doing that right now with some 6" Marx cars from eBay.

I remove the frame from the body.

Then I use a hammer handle inside the roof and slide it at an angle across the dents to remove them. Use a burnishing motion and have a semi-firm surface under the car roof. Leather, cardboard, wood work well.

Also take the axles out and straighten them. They are bent more often than not.
