Can The Machine Be Polished With An Eccentric Sander

How and what to polish a car with your own hands at home Service centers offer car owners dozens of types of polishes, but the cost of services makes many drivers think about how to polish a car at home.

Preparatory operations

The garage must be cleaned before work, removing dust as much as possible. Experienced auto mechanics advise against polishing the car at sub-zero temperatures and in heat (over 35-40 degrees). Before starting polishing, a number of preliminary operations are required:

  • Body wash (manual or contactless);
  • Removal of stains and stubborn dirt (oil, bitumen);
  • Pasting decorative parts (chrome, nickel, rubber, plastic);
  • Inspection of a clean body (the choice of abrasives, the granularity of polishing compounds depends on the degree of damage).

After washing, stains of bitumen, oils are clearly visible, which are removed by hand, mild solvents, degreasers, white spirit. In this case, you do not need to use screwdrivers and knives. After soaking the stain, it is easy to remove it with a fingernail or a plastic card.

In order not to damage decorative elements (glass edging, moldings, mirrors), they are pasted over with masking tape. Professional polishers also remove nickel-plated door handles, but it is not recommended for beginners to do this at the first experience.

Experienced lovers of independent work with the car, while polishing the body, also polish the glass of the car. Technologically, the operations differ little (only in the compositions of pastes and protective agents), having gained experience, you will be able to polish the glass yourself. At the first attempt to polish, it is better to glue all the glasses.

Reasons for the need to polish and restore paintwork

The main reasons for the need for polishing are natural aging of car enamel and dirt on domestic roads. All road debris raised by the movement of passing and oncoming vehicles leaves marks on the body of your car. Micro-scratches are difficult to see with the naked eye, but their accumulation affects the reflectivity of the varnish. noticeable on the paint are traces of hard sand, gravel, flying stones, roadside branches hitting the body.

can the machine be polished with an eccentric sander

The scuffs and dull color of car paint are caused by road chemicals, winter sprinkling of highways with salt, sand, and chemical reagents. Various bischofites and modified calcium have a destructive effect on the body paintwork. Acid rains, hail, dirty snow leave traces on the car enamel.

Oddly enough, but auto mechanics consider an important cause of scratches and scuffs to drive on an automatic brush wash. From regular cleaning with rotating brushes, body paint (especially soft enamels) loses its shine and tarnishes. And if the owner of a car wash saves on timely replacement of worn brushes, the hard ends of the bristles leave deep scratches on the paint. Road dirt is stuffed into micro-scratches and small chips, expanding and deepening the damage.

In addition to the loss of gloss and brightness of the factory color, all damage to the paintwork is dangerous with more serious consequences. Scratches, overlapping each other, completely cut through the paint layer and can become centers of rust, which will require expensive body repairs with repainting of the car to eliminate them.

Every driver wants to restore the perfect shine of the body and glass, but the services of branded technical centers and road detailing studios are not available to an ordinary car owner every two to three months. With limited financial resources, many Russian motorists have no other choice but to polish the car themselves.
