SANDING AND PAINTING:

Metal Surface Preparation:To prepare for polyester body filler the feather edges of both the old paint and theblack primer from the new panel must be sanded. This can be done manually or with anorbital sanding machine. A high quality refinishing job, for example on a virtually new car,must result in a very good finish quality, which means that comprehensive body filling and priming work with careful fine sanding will be required. Filling paste and hardener must be mixed before using. In order to achieve a perfect adhesion with the polyester body filler, the substrate must be degreased thoroughly using two clean cloths and degreaser. The joint between the old and the new panel can be made invisible using polyester body filler.

After drying the polyester body filler must be sanded preferably using dry sanding paper. The original shape can be restored easily by help of a sanding block. Before the spray filler is applied, both the old paint and the black primer on the new panel must be sanded which can be done manually or with an orbital sanding machine. While the new panels and repaired ones are being sprayed in the filler, the car must be covered to protect against overspray. Look at the picture to see the sanding and cleaning the surface after filling paste practices Before application of the colour coat the panels must be treated again with degreaser to remove all contamination. Masking is necessary to avoid overspray from the whole of coat on other parts of the car. The colour accuracy of the repair paint must be checked against the car colour. Forced drying at 60°C is possible to speed up the drying process. You must use mask when you make painting practice.
