The hardener is packed in a separate tube and is added before applying in a ratio of 2 - 3% to the bulk. Time frozen from 6 to 8 minutes. It is necessary to work quickly. The layer thickness can be up to 2 mm, provided that the first is much thinner.
To obtain a smooth and smooth surface, putty on the plastic is applied by a rubber spatula and each layer is cleaned. For independent work I recommend choosing mixes with high softness. The parts made of plastic are mainly rounded surfaces, the form of which repeats the tool when sliding and equalizing the composition. Metal canvas can scratch a softer part surface.
Grinding putty on plastic is performed manually. Insert the skirt in a special device. First large, then small. We do not recommend using machine and water. The first of its vibration can destroy the item. Water will make a putty viscous and worsen processing, may even remove the whole composition.

For climbing cracks and defects on internal parts that are exposed to loads and vibrations, I recommend using reinforcing plastic wipers with fiberglass. The polymer composition on a latex basis is sold in a ready-to-use form. It can be applied with a layer of 2 mm. The disadvantage in the impossibility of grinding and creating a smooth surface. The position corrects the use of finishing compositions without additives.
After grinding the surface of the putty, requiring staining, is covered with primer mineral, acrylic. Accelerate the drying of materials can be lamp. Temperature should not exceed 60 degrees. The minimum should be no lower than ten.

To close the holes in plastic and wide cracks, which will not be able to tighten the putty, I recommend using the glasswork. It passes on the surface and holds the material. For this, the surface must be projected and coated with glue composition or diluted PVA water. After that, mount the grid and give the mixtures to completely dry before putty.
