rev up your engines, today I’m going to
show you how this little machine can keep you from getting ripped off if
you’re buying a used car now this little carsys is a paint
thickness gauge and it’s a big deal these days because car paint has gotten
thinner and thinner here in the United States we use mil thickness and a mil
is a thousandth of an inch so you’re talking about really small and the
space itself is taken up on modern cars by various different processes sometimes as many
as 4 coats sometimes the metal is electric coated
then it has a primer on top of that then it has a color layer that you see and
then there’s a clear coat on top of that but when you add them all together all
these layers are only four to five mils thick which is four to five thousands of
an inch thick so you’re having too much stuff that you’re playing around with
and this is one of the reasons you really can’t get a modern car to look
that good repainting it the factory paint generally beats anything hands
down because they’re painted by machines and the robots can measure it perfectly
it’s pretty hard to get at that exact thickness unless you’re a robot that’s
programmed and they measuring with lasers and stuff they can get it really
accurate so a modern paint job really looks good from the factory that’s where
this little paint thickness gauge comes in handy let’s say you’re buying a used
car you can see if it’s still got the factory paint you can see if certain
areas have been painted over very easily like this first you just clean a little
bit and wipe it dry in case there’s anything on there that’s gonna make the
measurement wrong then you just turn the machine on its zeroing itself and stick
it on here we go and as you can see it’s four point eight
eight mils thick exactly between four and five mils now I know this hood has
never been repainted it’s a factory paint even though it’s twelve years old
somehow that’s perfect but watch this this fenders been repainted so let’s see
what it is what’s your here on a few spots
this one’s 4.8 this one’s 5.85 and way down here
it’s 6.0 so I know for a fact this fender got mashed in and had to be
replaced it was repainted as you can tell the
person who repainted it didn’t do such a hot job you got too wide of a range one
part is six mil one is 4.8 it wasn’t painted all that well it looks okay well
if you see it in the Sun you can see that the color doesn’t match either it’s
very hard to match colors no she faint the old car nowadays it’s almost
impossible to totally match a 12-year old car the old paint to the new paint
but you can see here the variance is too much it’s been repainted so you bring
something like this when you’re buying a used car you can check it all over
that’s basic we can’t tell how thick to paint is just by looking at it but this
machine it just does a great job and also as a zero correlation so you can
redo it every once in a while so you make sure that it’s really perfect
and it doesn’t matter if it’s aluminum or iron steel the Machine
calibrates itself so you want to make sure it’s working right turn it on and
then put it flat there’s no paint on it so it should be zero
there it is zero it’s perfectly calibrated zero Mills
and that’s for the iron steel weld it was aluminum that’s the same thing smart
on off this machine it knows that’s zero to know if it does get off as an ages
you just put it back on you push buttons and you can recalibrate it so it’s just
zero when you put it on the flat model now it only measures paint on metal
surfaces there’s still spoiler acts fiberglass put it on it won’t give you
any reading because there’s no metal inside it just stays with lines means
it’s not reading it’s really handy if you’re looking at a used vehicle if
there’s metal it’s gonna read right now let’s say in this case which has been
wrecked and bondo’d watch what happens when we read it we stick it on 70.70
mils what does that tell it tells me been bondo’d thick it’s real thick so
it’s been bashed in bondo put on it and then paint it over so you know you’re
getting a vehicle that’s recked had crappy bondo worked on on if
you like it and it runs okay don’t pay too much you said all that Bondo’s on
there it’s not still under there all right who knows how much Bondo’s all
over the car you could check the whole vehicle if you wanted like here and it’s
three point three so you know that’s more or less the real paint realize that
manufactures use different paint thicknesses on them so you get a base
reading on your car and you find that most of it is one reading like three
point three and then all those are a bunch more you know body works been done
it’s been repainted it can’t hide the paint thickness from this machine and if
you really want to be a fanatic about when your car’s painted and you’ll find
out there’s a big thickness difference you can tell the guy you’re gonna have
to strip it down and repaint it you didn’t paint that car right much thicker
on one part than the other means you didn’t do a good job when he painted the
vehicle take my Celica I bought it for 300 bucks at various colors cuz it had
been painted at a high school and the paint was peeling off by the previous
owner so I got one of these $400 paint jobs and of course they’re never gonna
be perfect we’ll check the top that’s 6.85 way too thick well check the side
that’s 4.05 pretty good thickness but really this was one paint job no cars
painted at once the top is much thicker than the side is we checked the back and
that’s only 3.22 the guy who painted the car he was all over the place with the
thickness of the paint, now it looked fine years ago and I got painted it the first time
but it’s gonna fade deferentially so if you’re looking at a car and you got one
of these gauges and you see these readings all over the place you know
it’s been repainted you tell the guy hey that’s a crappy paint job in order to do
that right you’d have to strip it down paint it that’s gonna cost thousands of
dollars so you offer them a lot less money and nobody can argue with its
results because it’s an accurate scientific machine hey you can even
bring those little pieces with you to show people how accurate they are no
one can argue this it’s the truth about paint on your car so if you’re buying a
used car or maybe you got in a wreck and you got your car painted or you just got
your car repainted one of these machine can keep you from being ripped off
big-time the truth is in this machine measuring the thickness and this paint
goes on modern cars guy said they’re getting thinner and thinner than the
older one so it has to be done right and this machine will tell you if it was
done right or not and since its mechanic Monday I’m giving away one of these cars
paint thickness gauges to have a chance to win place they’re clean non-offensive
comment on the youtube comments below and a winner will be chosen randomly by
computer get one of these cool paint thickness gauges so you never get ripped
off on body or paintwork again, so if you never want to miss another one of my new
car repair videos, remember to ring that Bell

  2. We used dry film thickness gauges in inspecting paint thickness in industrial settings. The specs may call for certain paint thickness for each application coat. When your talking about painting an entire plant, or a huge storage tank, you are getting into lots of money. The customer may hire an inspection company to assure their getting the proper protection, or paint thickness, and a quality job. At times the painters, applicators, will use a wet film gauge, and with knowledge of what it would dry out at, he knows how thick each coat needs to be. The inspectors can also assure the owner they got the proper number of coats of paint.

  3. I feel like if you were buying a pre-owned car and tried to use inconsistent paint thickness as a tool for haggling over price, they’d just tell you to get lost. They’re not hard up to find suckers to pay full asking price, and that’s the problem, even if you know how to negotiate. They can always hold out and find someone who isn’t.

  4. Is the paint being a different thickness necessarily a bad thing. I know it shows the car's been painted but will the paint hold up and look good

  5. Hey Scotty, thanks for that video. I live in Australia and I reckon that gadget would be great here. I'd love one to test it out on my paint work.. Cheers mate. S

  6. Aren’t the different measurements the result of feathering in the match? BTW, the dealers who provide the Kelley Blue Book Instant Cash Offer program use such a meter and will deduct from the offer based on the number of panels affected.

  7. Salesman: Oh yeah, that is a really cute little toy you have there. Price is still the same. Make a purchase or walk.

  8. This channel is growing on me, keep em coming Scotty!
    Thoughts on 2017 Ford Focus RS? I have one, built and tuned(i know you hate that lol) with a water/meth kit. I have replaced just about every plastic pipe etc with good quality aluminum etc. I want to keep the car a long time. Any other tips?

  9. That's really cool, can't wait to see all the customers sticking that to the side of their car at the body shop I work at lol

  10. AmmoNYC talked about using these as well and mentioned about checking the paint in the door jam to see what the paint thickness should be. Some paint and body shops don't repaint them.
