Hi, my name is Chris Springer and I’m with
the PPG Refinish marketing group and I act as an application specialist. Part of my role
is to develop application processes for repairing OE vehicles in the collision centers. For
years we’ve been teaching you to paint colors to full hiding, or to opacity. In the OEM,
they have driven a change in the way that colors are sold to customers, as well as the
way that vehicles are repaired in the shop. As much as 20 percent of today’s colors are
translucent colors coming from the OEM. And, what I mean by translucent, is the pigments
they are using have a level of transparency to them. The more chromatic, the more vivid,
the more vibrant the color is, the more likely it is to have a level of transparency. So,
the undertone or the primer color that the OEM is using becomes part of the final color
on that vehicle. What I’m going to do is demonstrate the process of repairing one of these highly
chromatic colors from the OEM, and do it in as little as three coats plus a control coat.
What you will see is the color matches, and the repair is 100 percent invisible. The transition
from where the repair was done to the exisiting OEM finish is impossible to pick up. So what
I have here is the repair that we’re doing today on a Toyota 3R3 Barcelona Red, which
I’ve identified as a very translucent color. What I have is two primer spots that have
been primed in the proper G shade for the color. The key to that color is eliminating
the hard edge of the primer surfacer. So with this repair being good solid surfacer, there’s
no burn throughs down to body filler, no bare metal exposed, the option that I’m going to
use here is to use our waterborne basecoat formulated to the correct gray shade to make
that transition from primer to OEM color. Let’s go into the mix room and I’ll show you
how to look up those colors. Every color in the PPG database has a complementary grayscale
that goes underneath it. Our color science team made the spectral grays of our primer
surfacers and our primer sealers in the colors of G1, G5 and G7 which can be intermixed back
and forth to create all five of the spectral grays, As a painter, to help you choose the
right color, one of the tools available to you is PPG’s variant deck system. This is
an example of a variant deck system that has been organized in a chromatic way, by color,
we also have this available by motor manufacturer. What this does is this provides you with a
paint chip that has been sprayed with PPG’s premium waterborne basecoats over the proper
grayscale to give you an accurate representation so when you go into our PaintManager� software
and mix a color, that this is the color you are going to get when you spray. So for our
repair in the paint booth we’re using the basecoat version of our G scale, but to find
out which G shade to mix up, we’ll go to the OEM formula. So we’ll press “Search”, “Standard”,
we’ll put in our OEM formula which in the booth is Toyota 3R3, so I put “3R3” in the
filed where “OEM Brand Code” is. Hit search, find Toyota, I can click “Prime”, which is
the variant deck chip that matched our vehicle. Hit “Continue”, and here is your formula page,
and on this page you have a alot of information. Not only does this give you your color box
number and show you where in the variant deck to find the correct color chip. It also tells
you in the instructions to use undercoat G5. So we’re going to go back to our main menu,
and search for the gray shade G5 instead of putting the OEM code in. Search for the Greymatic G5 listed in your
search results. And what that does is it brings up the waterborne basecoat version of that
G5 formula. So now we can go ahead and place our container on the scale, mix this formula,
and that’s going to give us the appropriate G shade for Toyota 3R3. (Sprays vehicle) For
demonstration purposes, with this translucent color, I’m going to show you what a typical
repair would be in a shop where you wouldn’t use a sealer or a ground coat to cover the
hard edge of your primer. This soft edge is the key to a translucent color success, Also
for demonstration purposes, I’m going to place a hiding sticker on the edge of the panel
here, You’ll notice that the hiding sticker will not disappear even though the repair
is invisible. Where we’re at is we’ve applied two coats of the application of our waterborne
basecoat, and you can start to see on the side that has the nice tapered, soft edge
of ground coat into the OEM has started to get perceived hiding, whereas this side here
that has the bare primer surfacer with no sealer and no ground coat applied is blatantly
sticking out where both have the same amount of paint on them, but the right side with
the ground coat is perceived to be so much further ahead. We’re going to wrap this up
and put one more coat of color on, go and do our control coat, and we’ll come back and
revisit the panel. Ok so now we’ve completed putting on three coats of our waterborne basecoat
and a final control coat, and what you can see here is the area that have the G5 ground
coat is 100 percent perceived hiding. The other side that had just the surfacer is pretty
obvious. Why I want to emphasize perceived hiding is remember for our demonstration we
put on a hiding sticker here. This hiding sticker is showing us that we do not have
coverage. Coverage is not important. Color match and an easy, invisible blend is important,
and that’s what we’ve demonstrated here. So it’s not simple to repair a translucent color.
Let’s recap what we did on this repair. We identified the OEM color as Toyota 3R3. We
went to the PaintManager� software and found that 3R3 calls for a spectral gray rating
of G5. Because the repair had no burnthroughs down to body filler, to bare metal, to make
that soft transition edge we opted to go with our waterborne basecoat in G5. Sprayed one
coat of groundcoat to give a nice transition from primer to OEM color. Came back in, put
three coats of color on to give the color in perceived hiding. Put one control coat
on to ensure color match, We applied two coats of clear and this repair job is out the door.
For a normal collision repair center, this is not going to be any extra steps or anything
out of the ordinary of what you’re used to doing on that other 80 percent of opaque colors.
Rather than going and spraying the ground coat, when you’re doing your repair work,
or doing your priming in the shop where there’s body filler where damage has been done to
the vehicle, you would mix your primer surfacer in the recommended G shade. And with that,
I hope that brings some clarity on transparency.
