In this step you will need two types of brushes:
- a flat brush to paint the front and side of theradiator.
- A brush with a curved handle to paint the inside of the radiator.
The brush with curved handle will allow you to paint the radiators without disassembling them, but they require a lot of patience and attention to use.
To paint a radiator you can choose a “radiator enamel” with a characteristic warm white color.
With the brush, cover the radiator with radiator enamel and let it dry waiting for the times indicated on the label. It is generally recommended to apply two coats of varnish to obtain a more uniform result.
For small touches you can use spray cans.

Ideally you should have a compressor and a gun applicator with a nozzle suitable for radiators. If you use spray cans, replace the standard outlet nozzle with one specifically purchased for paint the radiators.
