Everyone, welcome to our sixth and final episode
in our paint defect series.
My name is Kevin Ansell, application engineer at 3M.
In this episode, we're going to cover swirl marks,
what they are and what you can do to fix them.
[MUSIC PLAYING]
Before we get started, let's go over a few things.
First, make sure you're wearing the proper PPE whenever
using any of these materials.
You'll notice today, I'm wearing safety glasses, hearing
protection, nitrile gloves, and a half face respirator
with organic vapor cartridges and a particulate filter.
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 the link
to the safety and warranty information in the description
below.
Now let's get started.
When we talk about swirl marks or holograms
what we're really talking about is the aggressive scratches
that could be put into the panel whenever
you're using a wool pad for a rubbing compound step.
You want to have a pad that is suitable and aggressive enough
to completely remove any of those 3000 grit scratches.
Or if you don't use 3000 grit scratches, those 1500 or 2000
grit scratches.
Remove those scratches so that you have a fine enough finish
so that when you move on to the machine polish,
you don't have any of those scratches that are left behind.
When we're talking about compound swirls,
we're looking at those long arches
that are located in the panel.
That's coming from your buffer and your tool
that you're using to remove any of those scratches
from the previous step.
If you're seeing the little tick marks,
those could be from your DA steps
whenever you're using your 1500 grit or 2000 grit.
If you see those, you're going to need
to go back and spend a little bit more
time either compounding or using a finer grade
abrasive like our 3000 grit.
Then you can continue on making sure
that all of those scratches from the previous step
are removed before you can move on to the next step.
Having some swirls in the panel, that's OK,
that's all part of the process.
You really want to just make sure
that you are polishing long enough so that those swirls are
completely removed before you return
the vehicle to the customer.
Looking at this panel here, I don't see any of those core
scratches those 1500 to 2000 grit scratches or even
a 3000 grit.
Really all I'm seeing is just the swirls that
are left behind from the compound step and the wool pad.
All right, to fix this, I'm just going
to continue on with our paint finishing process.
I'll use a black foam pad with our machine polish.
And since this is a black panel and really shows
any of the imperfections that are left behind,
I continue on with our ultrafine machine polish
to completely remove any swirls that
are left behind on the surface.

So there we have it.
We have eliminated our swirls, eliminated
any of our defects to avoid any indication that this panel was
repainted in the first place.
That's all there is to it.
That wraps us up for our paint defect series.
