how can I remove fish eyes in my finish ?

You can't. It's the result of the paint gun being dirty. Strip the paint start over.

Painting Contaminants

Silicone is one; water and oil are the other major painting contamination culprits that cause fish eyes, which look like little craters where the paint pulls away from the centre, which occurs immediately upon spraying.

Fish eyes are caused by contamination of the surface to be sprayed. If the surface to be painted receives the correct preparation it should not cause issues

Clean the paint surface with one of the following products-

• DuPont PrepSol II™ or Final-Klean - spray onto a 100% cotton or a micro fibre towel and clean the surface, DuPont now also sells the Sonatra Line, which are essentially wipes/towels, pre-moistened with either Prep-Sol or Final-Klean, ideal for all high tech wiping applications, excellent in use both wet and dry with high absorbent capacity

• Dow Corning® OS-2 Silicone Cleaner and Surface Prep Solvent is a volatile methyl siloxane (VMS) fluid that is compatible with a wide range of materials. It will not harm most substrates, including plastics. OS-2 can be used to remove silicone-based; greases, oils, car wax and car care products, will soften cured silicones to facilitate removal

• SONAX Premium Class Paint Cleaner is a silicone-free paintwork cleaner that safely and effectively degreases the paint surface and removes smear films caused by silicone, oil and wax deposits, also ideal for the care and maintenance of scratch-resistant ceramic clear coats. It will considerably increase the durability of a follow-up sealing or protecting treatment

TOGWT is right. You can't just wash off silicone and many many "wax" products today contain it. You can't sand if off either. The products listed above are your only option. PPG makes an additive to help eliminate fish eyes but it wont eliminate the need to prepare/clean the service.
