Hey, everyone.
Welcome to our next video in our Paint Defects 101 series.
My name is Kevin Ansell, application engineer for 3M.
Today, we're going to take a deep dive into fish eyes.
We're going to talk about how they occur
and what we can do to fix them.
[ROCK MUSIC]
Before we get started, let's go over a few things.
First, make sure that you're wearing your proper PPE
whenever you're using any of these products.
You'll notice, today, I'm wearing safety glasses, hearing
protection, cut-resistant gloves,
and a particulate-filter respirator.
Second, this video is intended for occupational use
only, like in a body shop or a paint shop.
If you want more information, I posted a link
to our safety and warranty information in the description
below.
Now let's get started.
Fish eyes usually occur when there's
some level of contamination either in the air
or on the surface of the panel before you even
apply your paint.
This can occur in any level of the process,
whether you're spraying base coat, clear coat, what
have you.
And it's mainly a result of silicone, or oil,
or grease that's left on the substrate.
It wasn't properly cleaned, and it
doesn't allow the paint to properly stick to the surface.
It almost makes it so that the paint is resistant to the area
where you're trying to apply paint,
and there's just a little crater or a little area of resistance
where the paint doesn't properly adhere.
More often than not, this is going
to result in a repaint of the panel.
So what I'm going to show you here
is there is a small section on our panel
that there's a couple small pools where
we don't have our paint adhered to the surface.
I'm going to buzz that off with 800-grit abrasive using dust
extraction just to make sure that dust is not getting back
into the air.
And then, we will have the surface
ready to go so that we can reapply our clear coat.
Before I begin scuffing out my fish eyes,
I'm going to put a strip of tape down in the middle just
to separate what the panel looked like before versus
what it looks like after.

All right.
So, now, we've removed our fish eyes.
Made the surface nice and flat again.
We have sanded down.
We're still contained within our base coat.
For this application, we can go ahead and apply our clear coat
after we clean the panel with our water-based cleaner,
solvent-based cleaner.
And then, tack the surface just to be sure and be absolutely
certain that there's no contaminants left
on the surface.
It's important to try to identify
what was causing the fish eyes to occur in the first place.
It could have been somebody using
a wax- or a silicone-containing product outside of the spray
booth and some of those particles
could have landed inside the booth,
or if you have moisture contamination in your air
lines, if the panel is not properly cleaned beforehand.
You really want to make sure that you
can do anything you can to avoid this
from happening in the future.
Because any time you have to go back, and repaint,
and reapply clear over the panel, that's
time that's not spent as efficiently,
and you're not getting paid for that type of application.
So anything we can to prevent fish eyes from happening again
in the future, that's something that we're
going to try to achieve.
