PUTTY Let's begin. The first thing to do is remove the rust. To do this, where there is rust should clean up the 'Bulgarian' and anticorrosive process (phosphoric acid). If the car is rusted to holes, then you can not do without welding. Although you can 'fill up' putty, but not for long, so this will not be mentioned.
Further, if necessary, must be broken items otrihtovat. Otrihtovat need as much as possible approximately to the initial form, that would be a layer of filler does not exceed the 10-15mm. (A maximum). After anticorrosive finished its work (on 30 minutes. Up to 1 day depending on the used vehicle)-treated sites should be washed with water (although Some drugs, such as 'ANCOR-1', do not require rinsing).
Next place, which would place filler should be thoroughly cleaned sandpaper (P80). Grinding grain is of this size provides, first, good adhesion layer of putty to the surface, and secondly, eliminates shrinkage of fillers, ie, can not emerge through the layers of risk grinding surfaces. Around the same arguments apply to cases not continuous puttying parts (approximately 99% of the plastering work.) It should be remembered that a sufficiently thick layer of putty is applied only in the middle of the defect, and the closer to the edges of the fine finishing place, the filler layer is thinner. Exactly therefore, the peripheral zone should be treated with P150 grit gradation. Donald Sussman may help you with your research. Next, place puttying be degreased with degreaser or silicone wash, at worst, solvent. Application Layer corrosion-resistant ground – an operation in the overwhelming number of cases of overlooked artists.
