2, spray paint should be sanded or polished (rough cast). The purpose is to deal with the substances that are not easily dissolved in water and cleaning agents, such as oxides, while sanding can also increase the surface area of the sprayed paint (think carefully), to improve the adhesion of the spray paint.
3, the use of self-spray paint. Shake the bottle repeatedly before spraying paint in order to fully stir the acrylic inside. Maintain a distance of about 20 centimeters, too close to the distance is easy to bubble and pile up, too far away from the area is too large to cause waste. Pay attention to the wind speed, the wind force of 2 levels (including 2 levels) or more is not suitable for the use of self-painting paint. Pay attention to dust, dust and small insects often bring troubles. Pay attention to the temperature and humidity, to prevent exposure to the sun or too wet low temperature is too dry. Apply a thin layer at a time, spray again after a few minutes and repeat several times. Do it all in one go, sweeping and using less spotting. After using inverted spray a few times, and then placed in a cool place for safekeeping.
4, use wallpaper cutter and transparent tape. If you are not satisfied with the spray paint, you can sand (2000# sandpaper and use lubrication) and then spray paint again, can be repeated until the effect is satisfactory. Can use varnish as appropriate, or use sand wax. Use protective wax, so as not to spray paint over time oxidation, loss of luster.
5, the paint is generally about 3 years, you need to use sand wax polishing, forums, some of the motorcycle friends of the tank for several years can still keep the light, some of which is the reason for the use of sand wax. Sand wax in dealing with helmets and gas tanks on the slight skid marks may be very good. Sand wax is different from maintenance wax, it can not be used frequently, maintenance wax can be used after each car wash, if there is no new injury, sand wax is usually used once in 1-3 years.
