Causes
1. Insufficient surface preparation will leave undesirable particles such as dust, oil, old paint or water on the surface. As a consequence, moisture leaks down during painting the top coat and blisters emerge.
2. Water or oil remains in air pump or hose
3. Low adhesion between top coat and primer
4. Having the metal surface stranded for too long can add moisture on metal surface

Prevention
1. Thoroughly cleanse the surface before application
2. Use top coat and primer with high adhesion
3. Filter the water or oil, or drain the water or oil before application
4. Do not leave the metal surface too long before actual application

Solution
Peel or sand down to the affected area and refinish again
