Remove rust in the camera

You can polish away the rusty surface inside the film compartment if the rust is not heavy. It is an important procedure to save these camera as the chemicals in the developing process which may squeeze out and stay on the metal surfaces inside your Polaroid Land Camera. Those developing fluid is lightly corrosive and will get your camera rusty if you don't clean them after use.

If there is rust inside the compartment, you can use a #400 or finer sand paper to polish those rusty surface until all rust have been removed. The polished surface is clean and in shiny steel colour. You can check the condition of the metal and verify if the rust is too heavy that the metal is almost 'eaten' away.

After you polished the rusty part, you will need to paint the polished surface in black. The painting serve the purpose of protection and also reduce the reflective surface inside the camera.

In my camera, the rusty part is close to the rollers and I need to remove the film guider to have the polished area cleared for painting.

3 screw have to be removed. There are 2 small spring underneath the top cover. You must be very careful not to lose them as they are vital to have the film guider in the centre position of the rollers.

Use a small tray to keep those small parts, you cannot find some of these pieces unless you bought another second hand Land Camera for them.

Although spray paint may have better cosmetic result, I prefer to have the area painted. the paint I used is the TAMIYA Acrylic Paint ( Flat Black ). Several layers have to be added to have nicer and stronger finishing. Compared to the original coated black surface, the new paint seems a little bit darker. 

Anyway, protection is more important than outlook. Therefore, I will say the job is done.

Leave the painted surface dry completely after applying extra layers of paint. You can polish the paint away for repainting if it is needed.

The outlook is much better now compared to the original rusty chamber. This maintenance will give your Land camera extra years in services.
