Painting precautions - painting method: grease treatment before painting is very important. It is not correct to see others using self-spraying paint, often simply cleaning, or wiping it with a rag, or even spraying it directly.

The correct way is to use detergent, wash carefully, not only to pour off the dust, but mainly to clean off the grease, including engine oil, sweat, etc., these grease is the biggest enemy of self-spraying paint, one of the main reasons for easy to fall off is grease. Don't trust your eyes, just because the oil you can't see doesn't mean it's not there.

It should be sanded or polished (rough polishing) before painting. The aim is to dispose of substances that are not easily soluble in water and cleaning agents, such as oxides, and at the same time, sanding also increases the surface area of the painted object (think about it) and improves the adhesion of the paint.

The method of self-painting use. Shake the bottle repeatedly before painting so that the acrylic inside is stirred thoroughly. Keep a distance of about 20 cm, too close distance is easy to bubble and accumulate, too far away area is too large to cause waste.

Pay attention to the wind speed, wind force level 2 (including level 2) and above is not suitable for self-spraying paint. Pay attention to dust, dust and small insects can often cause annoyance. Pay attention to temperature and humidity to prevent exposure to the sun or too humidity and low temperature and too dry.

Spray a thin layer at a time, spray again after a few minutes, and repeat several times. It should be done in one go, and it should be strafed and less point-shot. After use, spray upside down a few times, then store upright in a cool place.

Use a wallpaper knife and scotch tape. If you are not satisfied after painting, you can sand (2000 sandpaper and use lubrication) and paint again, and repeat many times until the effect is satisfactory. Varnish can be used as appropriate, or sand wax can be used.

Use protective wax to avoid oxidation and tarnishing of the paint over time.

The paint is generally about 3 years, and it needs to be polished with sand, and some of the motorcyclists on the forum can still keep their tanks bright for several years, and some are the reasons for the use of sand. Grease wax can work well on handling slight slip marks on helmets and fuel tanks. Sand wax is different from curing wax, can not be used often, curing wax can be used after each car wash, if there is no new injury, sand wax is generally used once every 1-3 years.

For the same job, it is best to choose the same batch and color of painting, so that there will be no color difference, and the effect will be better. Before painting, be sure to do a test spray to see the color effect, so that the painting can achieve the desired effect. Before using the spray paint, shake the spray can properly for about two minutes, so that the paint in the spray can can be evenly distributed, and then the paint can be better sprayed.

When painting, be sure to take the spray can to a certain distance from the surface, and then use a uniform speed to paint, so that the painting can be more uniform, and can not be sprayed at one point all the time, so as to prevent the paint from staying. After the painting is completed, if the paint in the can is not used, it must be sprayed back, so as to prevent the gas in the can from blocking the mouth of the can, and then the spray can will not be scrapped.

For unknown materials, please test spray in a small area first, and use it if there is no adverse reaction after 10 minutes. When painting, the aerosol can must be kept upright and the angle between it and the horizontal plane shall not be less than 45 degrees.
