Solution 

Finish off a bad adhesion.

1.Solvent evaporation is not complete
2. Primer contaminated
3. Solidification incomplete
4. Paint is not supporting one.

1. Improve the leveling of temperature and time, reduce film thickness
2. After the primer coating material to keep clean, do not touch hand
3. Check-curing equipment is properly
4. Replacement Topcoat

Even at the end off a bad adhesion.

1.Primer attached to poor
2. Topcoat to bite at the end of one.

1.Adjustment or replacement of primer
2. Paint and primer do not match, use the same factory matching paint

Particles, Ma points

1. In the air more dust, impurities
2. Paint contaminated one.

1.Clean Air
2. With 500 mesh filter, paint

Hardness bad one.

1.Energy is too low, curing is not fully
2. Paint is not supporting
3. Painting itself is a somewhat less hardness.

1.Adjust the curing energy
2. Supporting the use of coating
3. Adjust the coating formulation

From shrinkage, a crater.

1.Primer contaminated
2. Compressed air contamination
3. Contaminated paint
4. Spray gun, spray pipe pollution

1. Replacement of contaminated paint
2. Check the oil-water separator
3. Adding some shrink holes in the paint additive
4. Clean spray gun, pipe
