Remove the old paintwork, remove the soil and align the surface. After soldering, it is necessary to carefully polish the seam, refining existing irregularities. Do not attempt to get the perfect surface without a single defect, as there is a risk of thinning the bumper and additionally deform it.

Upon completion of the work, remove the dust accumulated on the surface by processing the bumper with a special cloth or blowing compressed air.

Finishing, Painting Enamel, Polishing

After processing the orbital-grinding machine, the manifest will be removed from the smooth surfaces, but will remain in the depressions and will be very noticeable. Processing the element before the manifestation of the soil, you immediately detect all the shortcomings. Eliminate defects are necessary with the help of special mixtures, such as nitro-ship. On problem areas, the agent is applied only after their cleaning and primer. Allowing the nitro-naval to open, perform polishing.
