Not expensive to fix but
impossible to ignore ; stone chips and other minor damage are not only
aesthetically displeasing they look unsightly and once they begin to
accumulate, especially on dark coloured car. But worse still, because the stone
chips, scratches and scuffs have penetrated the clear coat, you car will be
prone to rust.
Paint ages and fades due to ultra violet radiation exposure,
which causes photo degradation (fading). This happens to both the colour and
clear but some colour change more than others; matching paint colours is an
art. Combine the base colour coat with
flakes and tints then add a few costs of clear, some tinted and some not.
3M Finesse-It Hand Sanding
Pad.
This 3M product is a small 1 ½-inch (36.5mm) hand held sanding
pad and is used with our 3M micron abrasive discs typically to remove micro
imperfections on the repaired dent, or can be used to gain a "read"
of the dent by flatting the top of the dent, this usually shows any highs or
lows left over.
Repairing Paint Chips
It is important to properly
set customer expectations; most people will wrongly assume that a paint
touch-up repair will make the paint perfect.
It won't. You must explain that
paint chip touch-up does not remove the chip; it simply makes it the same
colour as the vehicle. You must make it
very clear that your paint touch-up service is a quick and inexpensive
alternative to going to a body shop to have a fender, hood or door repainted.
Why repair paint chips and
scratches; to improve the vehicles appearance, to prepare vehicle for lease
return, increase retail value and to protect the vehicle from further
(corrosion) damage. Chips and scratches aren't just aesthetically unpleasing,
the exposed metal underneath may be prone to rusting or additional chipping.
Fixing these spots with touch-up paint is an easy step in protecting your
investment-
If your repair paint is a good match you can slowly add layers
till it's slightly higher than the surface of the original surface. Then you
can use fine sandpaper to blend it and polish the area. Of course test on a
hidden or low spot on the vehicle to be sure the repair paint and the original
paint will sand and polish well. If either paint doesn’t take to buffing, then
the best you'll be able to do is fill the spot with as close a match as
possible and then leave well enough alone.It’s a good idea to have a bottle of touch-up paint available so that you can immediately touch up any scratches before the corrosion process begins. Do not try to paint over rust; always treat it first by sanding or by applying rust inhibitor paint. Use rust converter as the primer coat if the scratch (chip) is down to bare metal.
Methodology
Apply
isopropyl alcohol (ISP) to a Q-tip and dab on the rock chip or scratch a
few times. - Take a clean
towel and dry the paint chip.
- With a
utility knife cut the paint around the edge of the chip, the edge of the
paint chip indentation will be slightly higher than the surrounding area
and/or the edge of the chipped area
may have separated from the metal surface or there could be some wax/dirt
in the area or the paint may have oxidized on the edges (it is not absolutely necessary, but it
does improve the results and will avoid leaving a dark outline)
- Angle your
blade toward the centre of the chip and press down gently. Work slowly and
carefully, removing a small piece at a time, it’s not necessary to remove
a lot of material. Sand the area
with a Wurth
spot sanding pen, and then clean the area with isopropyl alcohol (IPA) and
then allow it to dry.
- With painters
masking tape cover the area surrounding the scatch
- Use Nikkens
™3000
grit finishing paper and a Unigrit Sanding Block to remove
any rust
- Or a Proxxon
Mill/Drill Unit
Micromot 50/E – Handheld_Tools
- Use an AutoSharp
paint pen
colour matched to your vehicle. The pen itself is very easy to use. You
simply shake it, depress the felt tip a few times to start the paint flow,
and then begin to "colour" paint into the damaged areas, much
like you would highlight a section of text in a book.
- Do not to try
to fix the chip in one application, apply a small amount of paint and
ensure that you cover a small area surrounding the ‘chip’, allow to dry,
repeat over a couple of days. Once the painted area is slightly higher
than paint surface, allow to dry.
- Once
completely dry, using a Nikkens™ 3000 grit
finishing paper and a Unigrit Sanding Block (previously
soaked for 4 hours or overnight) to ‘feather’ (see note ) and level
touch-up paint with the surrounding paint surface
- Use Woolite® or a car
shampoo on the chip repair for lubrication.
- Wet-sand
the raised paint dot by using blue masking tape and a centre punch; with a
1/8-1/4 -inch hole punched into it centered over the blemish and then use Wurth Spot
Sanding Pen or 1500/2500 grit sandpaper on the end of a new
pencil eraser to bring the paint thickness down to the surrounding level.
- Use a very
light pressure on the sanding block, lightly wiping the area often to
check your progress
- Next, using a
Nikkens™ 3000 grit finishing paper and a Unigrit
Sanding Block,
using the block in one direction only, feathering the edge out into the
surrounding area. Wet-sand
to bring the surface back to level with the surrounding area.
- Do not use a
circular motion (it will produce swirls) or a back and forth motion and
ensure the sanding block is always wet
- Keep the area
well lubricated with water and shampoo; otherwise it will dull the
paint. Once the surface appears
level, use a block to squeegee off the excess water / slush (3M™
Wetordry™ Rubber Squeegee, P/N 05517, 2 ¾-inch x 4 ¼-inch) If the water you are using has a high
mineral content, don't let it dry on the car, as it could leave spots
which may bleed through the new paint.
- Dry the
surface with a clean towel and inspect with your fingertips.
- If you can feel
a high spot, repeat the sanding / feathering process.
- If done
correctly, you will hardly notice the repair.
- A good car
polish (Menzerna Intensive Polish or Menzerna
Final Polish II
) will restore the paints lustre
- Finally apply
wax/sealant protection
Note
- Paint blending is basically painting an area larger than the
defect and then blending or feathering the clear to match the surrounding
paint, then wet-sand to bring the surface back to level with the surrounding
area.
Run Razor -
This cleverly-designed tool will take care of any problem areas that crop up
toward the end of the painting process.
Run Razor holds standard
razor blades at a precise angle to shave down semi-hardened runs, sags or dust
between colour and clear coats. Just
pass it gently over the surface, dialling down the blade position indicator
in.001" increments until the imperfection is gone –Eastwoods

Paint
chip and scratch repair technologies, is both a chemical and mechanical
process, once the touch up paint has dried, The Blob Eliminator® will
re-soften the paint, and the light rubbing mechanically begins to
"smooth" down the excess paint, with the touch up paint now
appearing on the cloth
- Langka
and Metallic Paint-the
reason metallic looks different after using the product is the metallic
flakes migrate to the upper level of the paint surface while setting
up. To counter this, use the blue
sanding card on edge immediately after applying the touch up, like a
razor. This will remove most of the touch up while the metallic flakes are
still suspended evenly throughout the paint, smearing the excess across
the local area. Let dry and use the Langka to wipe away the smear tail
left across the original (OEM) paint. - http://www.langka.com

- Touchup123- Use
detailer’s clay on panel to be treated, Wipe on Final Touch Compound to
prep surface, Wipe Colorfill on ENTIRE panel to cover all the blemishes,
Wipe on Final Touch Compound to remove excess Colorfill, Wipe off haze of
Final Touch Compound to leave a polished shiny finish, Touch up any
leftover larger chips with a brush (can be built up and smoothed out later
with Final Touch Compound if desired)
Metallic paints, silvers and
gold’s, have to be applied with care to avoid problems with the "colour
flop". Colour flop is the term given when metallic flakes in the chip
reflect light giving you a lighter or darker appearance. This is a variable
that cannot be controlled, for best results; shake the paint very well to get
the metallic flakes evenly distributed before you apply
