Remove the bulky and heavy radiator for painting not every can. Plus, this will take an extra time that you want to save while repairing. Therefore, painting the radiator “on the weight” is an excellent option for those who want to save their strength and time. Before the painting battery “on the weight” should be carefully cleaned. And although it is not necessary to make this procedure carefully under such conditions, but it is still possible to achieve the maximum effect. To do this, take advantage of a special nozzle for a drill or a brotca in the form of a rash. This method of stripping is sufficiently dusty and dirty, so you need to be prepared for the fact that the scratched paint will fly throughout the room.
If there is no such nozzle, you can resort to a metal brush and clean the radiator manually. More attention should be paid to those places where there is a rust, as it is potential radiator wear. But it is also possible that it can be just spots from dirty droplets of the resulting condensate.
For painting of the radiator, it is worth using a brush with a curved handle, which will allow to cry even hard-to-reach places. You can paint as a special enamel for radiators and any other acrylic enamel. You can also resort to paint in aerosol cartridges, but it will be a more expensive procedure, although fast and convenient.
