Fisheye in Cerakote

So today this happened...



A little background, then I'll explain the process of how we narrowed down the culprit, but we are still unsure of the exact cause.

We have a SIG 1911 we are Cerakoting Gloss Black. Did the frame and slide last week, and the guy wanted it "extra glossy" so I tried various polishing compounds on the slide to give it more shine, but it just didn't work. So today we blasted it down to recoat. Same bottle of Cerakote, same hardener, same gun, and we had fisheyes all over the slide. Now the testing comes.... using an ANI 0.8.

--- Test 1: clean the ANI gun, remix Cerakote, clean the part better (much better), try again...
--- Result: Fisheyes on the part

--- Test 2: Spray a speed shape with what's still in the ANI gun (bare speed shape cleaned with isopropyl)
--- Result: Fisheyes on the speed shape

--- Test 3: Clean the ANI gun in new thinner direct from a new 5 gallon bucket and in a new paint cup. Mix more gloss black Cerakote, try a different airline, another new clean speed shape
--- Result: Fisheyes on the speed shape

--- Test 3: New gun, LPH 80, thoroughly cleaned, more gloss black Cerakote,
--- Result: Fisheyes on the speed shape

--- Test 4: Original ANI Gun, OHW Brite Green on a new clean speed shape
--- Result: NO Fisheyes

--- Test 5: Clean original ANI gun, Different Cerakote color (same hardener)
--- Result: No Fisheyes

--- Final test: Clean original ANI gun, remix Gloss Black after thorough mixing (just in case)
--- Result: the fisheye breakout you see in the photo above

So... we narrowed it down to that one bottle of Cerakote Gloss Black being contaminated! We just used the exact bottle last week with perfect results. No idea of the ultimate cause.

    Actually, that is NOTHING for testing... That could be done in a good solid day. The reason I know so much about fisheyes?... I tracked an outbreak down that lasted from November till April for 2 years in a row. To say it cost my company a million probably doesn't touch it. THIS is why you test one thing at a time, THIS is why you isolate IMEDIETLY. Good job in tracking down the problem Joe.

    And sometimes paint can be contaminated from the factory, or some put a lid back on that got "dirty". You may never know what happened, but at least it looks like you found it.

    Yeah I'm sure the testing could have been more thorough. There were some instances where we changed 2 things at once, and we are also lucky we were able to isolate some things quickly. Like both the airlines to the booth for example. We also had a guy spraying Matte clear in the booth and had been painting/clearing all day. So I was fairly certain the air was ok. This process took place from about 2-5:00pm yesterday. Not bad.

    As far as the contaminant within the Gloss Black paint? Absolutely no idea how it happened. It's mixed w a hardener so leftover paint wasn't added back into the bottle. It's mixed in small quantities (in a graduated cylinder on a gram scale). But the lid could have definitely been the culprit. Who knows. At least we can get it out of the shop now.

    Thank you for the thread Joe...those things will make you question your sanity...

    Dirty fingers on the cap I'm guessing- very rare however, thank goodness

    Yeah, I have no idea. David is the one that sprays/mixes Cerakote. He's usually solid w/ his techniques. But it had to be something and he was the only one to use it. It's a mystery we will probably never completely solve.

    Hey Joe !!!! Theres this guy on the forum that's been doing cerakote for a long time ya know ????? hint hint !!!lol

    had the same thing happen with safety orange. I knew I was going at it right ....... Called cerakote and they sent another lot number to me overnight with no questions and tested the lot that I had. Two days later called back and said it was in fact contaminated and they were destroying that lot..
  • MidOhioHydrographicsMidOhioHydrographics Posts: 8,288Member, Moderator, Business Ninja El Moderator
    Nice! I have a call in to them. They were checking this lot also. I'll let you know what they say.
  • SreynoldsSreynolds Posts: 1,169Member ✭✭✭✭
    Did u meet a guy named camron at the training? @MidOhioHydrographics
  • MidOhioHydrographicsMidOhioHydrographics Posts: 8,288Member, Moderator, Business Ninja El Moderator
    Not that I can remember. I'm horrible with names. I remember Tom, Remington, maybe a Daniel and a Ryan... not 100% on those last two.
  • MidOhioHydrographicsMidOhioHydrographics Posts: 8,288Member, Moderator, Business Ninja El Moderator
    Oh and the new bottle is already here. Hopefully it's all good!
  • SreynoldsSreynolds Posts: 1,169Member ✭✭✭✭
    Ill bet it is......

    Those fish eyes appeared immediately right??? And was that H series ?? Im assuming it might have been C since its on a speed shape unless u were just playing/testing
  • MidOhioHydrographicsMidOhioHydrographics Posts: 8,288Member, Moderator, Business Ninja El Moderator
    Yes, it's H series. Just using a clean speed shape as a test substrate. We just threw it away after. And yes, appearing immediately.
  • SreynoldsSreynolds Posts: 1,169Member ✭✭✭✭

    Just sprayed with the new bottle. No issues.
  • onehitwonderonehitwonder Posts: 2,539Member, Business Ninja ✭✭✭✭✭
    .......and people want to start their own paint companies.....
  • MidOhioHydrographicsMidOhioHydrographics Posts: 8,288Member, Moderator, Business Ninja El Moderator
    It's just mixing chemicals... how hard could it be? Saw a guy on YouTube do it in a bucket outside.

    Cerakote also confirmed their samples of the same lot are fine. Had to be on my end. I think David added WD40 to give the Cerakote even more lubrication properties.

    @MidOhioHydrographics or @Sreynolds when you cerakote do you clear then bake or are you baking the paint? Just curious have never followed this process
  • MidOhioHydrographicsMidOhioHydrographics Posts: 8,288Member, Moderator, Business Ninja El Moderator
    It's a bake on coating. No clear/topcoat required.
