You can also use the so-called GOI paste. In normal condition it is a solid substance, but it can warm up to clay and in this form applied to the felt disk.
There is a budget option for cleaning chrome parts, rusted: a soft cloth moistened with ammonia solution or turpentine, apply powdered chalk or tooth powder and gently clean the item. After processing, the cleaned place must be cover with a transparent varnish.

After polishing degrease the surface. Use organic solvents or alkaline solutions, which must initially be heated. Give this stage particular importance, it depends on the durability and quality of chrome plating applied.
Apply to the volume, the binder layer of the soil, which after drying, leave on the surface of a translucent vitreous cover. Be careful to avoid drips. Layers can be several, it all depends on how quickly the surface becomes evenly covered. Wait for complete drying of the soil, which is about 1-2 hours at a temperature of 60-65°C. At home you have to wait about 7-8 hours. If the item is complex, the metallization need only the following day after priming.
With a special spray gun swipe rinse the product with distilled water. Then apply a special solution on the disc that mixes the reductants and chromium, and rinse again. Start plating with the lower portion and move to the top as the formation of mirror coating. The remaining water, remove with compressed air, use air gun.
Dry the item for half an hour at a temperature of 40°C and at room temperature, the drying time increases to 3 hours. After that, apply several coats of protective varnish. The first layer are raspylenie for their application, use a small amount of the composition.

Final polishing is carried out fine grinding of the powders.
Metal can be polished using special polishing pastes that include chalk, limestone, diatomaceous earth, dolomite, chromium oxide, aluminum oxide and iron oxide.
Thus the surface of most fine finishes achieve a friction piece of wool or felt , oiled with a special paste. After polishing this surface will get a mirror Shine.
For the preparation of pastes for polishing metals take paraffin 20 g, 10 g tallow, technical fat, 3 g and micropowder M 50 - 67, mix All ingredients until homogenous.
