How to spray auto refinish paint:
1 - Color paint layer
The color paint spraying is divided into three sprays: the first spray is mist spray, and the gun speed can be relatively fast, so that the repaired area or the whole car can be sprayed as thin as a mist, and the color paint can adhere to the primer film; The second time spraying covers the primer or putty layer, showing the colors. The speed of the spray gun can be slightly faster; The third time spraying is to correct the uneven spraying caused by the second time spraying. Generally speaking, it is the standard that the color of the repaired area or the entire car should be uniformly covered.
2 - Clear Coat/Varnish

You can spray the varnish when you touch the coating film lightly with your fingers and do not stain the color. If the paint surface is rough or prevent dust, it can be wiped with dust cloth and compressed air while blowing. After wiping, use a degreaser agent to degrease.
2) The first spraying of the varnish is mainly mist spraying. It should not be sprayed too thickly, and sprayed to the extent that a little gloss can appear. The speed of spray gun can be slightly faster.
3) The second time of spraying is for decoration, needs to show gloss. Pay attention to the flatness and gloss. Use the two-pass (back and forth) spraying method to spray overlapping, and the spray gun runs at a normal or slightly slower speed.
