Paint defects

Orange peel / poor flow(Surface texture resembling orange peel)
Cause:
Paint viscosity too high.
Fast, highly volatile reducers.
Incorrect nozzle size.
Spray gun too far from object; not enough paint applied.
Spray pressure too low (poor atomisation)
Paint film too thin
Spray nozzle too small
Flash-off time too long between coats

Prevention:
Set the right spray booth temperature.
Check and maintain spraying distance
Keep spray gun within the recommended distance from the object
Ensure spray pressure is as recommended
Always apply wet coats
Adjust paint viscosity as recommended
Choose correct hardener and thinner (temperature table)
See tech data for correct choice of spray nozzle
Allow a long enough flash-off between coats
Use appropriate surface modifying additives

Remedy:
On small surfaces, sanding and polishing are possible.
On large surfaces, sand down the texture and respray
