Fish eyes are normally caused by a contamination on the panel that repels the the paint - often silicone.
That additive contains silicone - I tried it once but it made the fisheyes worse. Wouldn't use it again. Best advise I've had is flat down, clean with brake cleaner, then respray the coat, though if you only have one or two I'd be inclined to try to fill them up with a small brush then polish.

I would have thought applying paint, even a touch from a brush would be rejected???. God only knows where this came from, the coat before was fine 20mins later same gun & contents this happened., mystery eh.

ive never had them appear only on the last coat, did you mix it in a different container i usually find if you get them they are there from the begining.
that said i havnt had any for years
just read your other post sounds like the tank got contaminated before your last coats did you polish it in between or even touch it with something

Once used, isn't the gun only fit for using the additive afterwards? Because the additive is silicone. Sure I've read of someone/where binning guns once used, in case of mucking up normal jobs in future...
Was there any WD40 or similar sprayed in the vicinity by any chance? Or air tools (exhausting oil mist), anything like that? Hose used for air tools also?
Are these close to your decals...? Ones I used needed 24hrs before clear, to let them dry/glue get itself sorted etc.

Quite understand and totally agree with what you are saying. Final coat 20mins or so after first one which showed no signs of fish eyes, the final coat was given with the same lacquer left in the same gun. The tank wasn't touched and is in a dedicated booth, mystery. I'm hoping that they will compound/polish out as they are in the last coat, we'll see. perfect job spoilt, just me too particular maybe.
Trouble is it's Jet Black and do they show.

i wouldnt have left it 20 mins between coats 20 mins is quite a long time 2k starts getting tacky quite quickly.
silicone has got onto your work somehow you need to work out how.
did you leave the spray area inbetween
did you use fast activator ?

Yes & yes.
No obvious contamination source, the decals were on around a day as advised by the supplier, they aren't a problem. I have an air polisher on the way, I intend to buy a dedicated hose for it to avoid problems from the lube..

have a closer look with a magnifying glass sometimes specs of dust can have a similar apperance to silicone contamination, worth a look
Never been used for anything other than 2k, I am meticulous with cleaning my equipment/draining tank & filters etc. Would just like to know for future projectes.
Thanks all for your input.

Did you use panel wipe before painting ???

Many deodorants & hair products contain silicones and similar substances, Their use is usually banned from paint shop staff.
I had an issue when painting a bonnet (celly) where just one fish eye appeared in the final coat. I used Malcom's idea and put a drop of paint in it with a coctail stick as soon as i had finished the coat, then de-nibbed it when dry. I have tried to find it since with (thankfully) no joy! The only thing i noticed while painting was a fly mooching about, possibly it had walked in something in the garage, then on the bonnet.

Did you have a burger or sandwich and not wash your hands ?
Sound like a solution to my problem this time, presumably the fish eye didn't reject the touch in?, usually you have to flat right down to source and eliminate the cause. Still could flat down, as mine was in the last clear coat, just a bit wary about polishing too far and go through, just to remove these.
