Waxing

The required colour may be prepared mixing the basic colours in the proportions given in the applicable colour formula. The enamels obtained in this way do not have the viscosity suitable for use; before use they should be mixed with a catalyst and thinned to the proportions indicated by the manufacturer, using a rod scale.

It is extremely important to use paint at the correct viscosity to avoid certain defects (running, pinholing, etc.).

Before application, check that the colour of the prepared enamel corresponds exactly to the colour of the vehicle.

Waxing

This is an extra wax oil-based protection for boxed components; it prolongs protection against corrosion over the course of time and is applied through special holes in the body. Refer to the diagram of page 117 for the areas involved.

Foaming

The purpose of foaming is to prevent the passage of swirling air and to sound deaden the components concerned in the treatment. Refer to the diagram on page 121 to locate the areas involved.

PAINTING OF CHANGED FIXED METAL PART (complete cycle)

Below is the sequence of operations concerning painting operations for a changed fixed sheet metal part:

1. Preparation (washing, sanding and cleaning)
2. Filling
3. Sanding
4. Masking
5. Primer Coating (on bare metals)
6. Sealing
7. Undercoating
8. Sanding
9. Masking
10. Coating with paint (base + transparent varnish)

– Wash the area concerned, dry sand the cathodophoresis protection, blow with compressed air, clean with a cloth soaked in silicone-proofing product and dry accurately.

– Fill any imperfections and leave to dry completely.

– Sand, level the filler and accurately clean the treated surface.

– Mask the necessary areas, apply the Primer on the bare metal and leave to dry in the air.

– Apply the specified sealant on the jointing areas and dry.

– Apply the undercoat and spy coat (paint).

– Dry sand, remove the masking and blow with compressed air cleaning again with silicone-proofing product.

– Mask the area surrounding the sanded surface and suitably cover the remaining parts of the car.

– Blow with compressed air and clean the surface with Tack-Rag.

– Apply the paints (base + transparent varnish) prepared previously (for the times between coats, follow the manufacturer’s instructions).
