00:00:12:16 00:00:14:01
Let's talk about fisheyes or
00:00:14:02 00:00:15:01
craters.
00:00:15:20 00:00:16:16
Who? That's.
00:00:16:17 00:00:17:20
That's a tough one, right?
00:00:17:21 00:00:19:21
That's the one we all struggle with.
00:00:19:22 00:00:21:09
We struggle with it because it's so
00:00:21:10 00:00:22:21
hard to troubleshoot.
00:00:22:22 00:00:24:07
First, let's talk about what is a
00:00:24:08 00:00:26:02
fisheye? Well, Why do we call it a
00:00:26:03 00:00:27:03
Fisheye? Or a creator.
00:00:28:04 00:00:30:18
It's a surface tension.
00:00:30:19 00:00:32:06
void Right.
00:00:33:12 00:00:35:05
Fish I somewhat because it looks
00:00:35:06 00:00:37:21
like a fisheye. I crater.
00:00:37:22 00:00:40:03
It's dipped down into
00:00:40:04 00:00:41:04
the
00:00:42:00 00:00:43:00
into the coating
00:00:44:07 00:00:47:03
separation surface tension
00:00:47:04 00:00:48:03
void.
00:00:48:25 00:00:50:06
So what are some of the possible
00:00:50:07 00:00:51:06
causes?
00:00:52:03 00:00:53:12
Silicone contamination,
00:00:54:14 00:00:56:15
oil contamination,
00:00:56:16 00:00:58:15
excessive moisture in your coating.
00:01:00:21 00:01:03:04
Where do we start troubleshooting?
00:01:03:05 00:01:04:00
First of all, look at your
00:01:04:01 00:01:05:00
environment.
00:01:05:20 00:01:07:21
Make sure we're not having
00:01:07:22 00:01:09:13
a new built, drifting or built
00:01:09:14 00:01:12:11
cleaner that we haven't had before.
00:01:12:12 00:01:13:22
Greases, oils,
00:01:15:05 00:01:17:10
sprays, sprays like
00:01:17:11 00:01:19:08
WD 40 in the air,
00:01:19:09 00:01:21:16
aerosol cans, silicone
00:01:21:17 00:01:23:01
wristbands that will also cause
00:01:24:12 00:01:26:13
some voids
00:01:26:14 00:01:27:20
or fish eyes.
00:01:27:21 00:01:29:06
Check your air supply as well.
00:01:30:18 00:01:32:13
We're getting moisture and oils
00:01:32:14 00:01:34:09
through our air lines coming to
00:01:34:10 00:01:36:04
our finishing area.
00:01:36:05 00:01:38:05
Those oils will also cause that
00:01:38:06 00:01:40:02
void, that fisheye air, that
00:01:40:03 00:01:41:04
crater. Anything.
00:01:41:05 00:01:43:12
We're lubricating our equipment
00:01:43:13 00:01:45:07
with all
00:01:45:08 00:01:46:15
those things, we need to take a look
00:01:46:16 00:01:47:15
at
00:01:49:06 00:01:50:10
moisture and coatings.
00:01:50:11 00:01:51:12
How do we have moisture and
00:01:51:13 00:01:52:12
coatings?
00:01:53:13 00:01:55:24
Check your check your
00:01:55:25 00:01:57:11
your coating.
00:01:58:11 00:02:00:05
Are we reducing it with a
00:02:01:07 00:02:03:03
certain solvent that likes
00:02:03:04 00:02:05:03
to draw moisture
00:02:05:04 00:02:07:01
and decay and decay loves to draw
00:02:07:02 00:02:08:01
moisture in.
00:02:08:21 00:02:10:21
These are a few possible causes
00:02:10:22 00:02:12:04
of fish and cratering.
00:02:13:07 00:02:14:15
A few solutions for you to take a
00:02:14:16 00:02:15:15
look at.
