The repair
of a scratch and a chip are the same. A scratch
is merely a chip on uni-directional steroids.
The only problem with a scratch is that it
takes more time to be able to blend in the
new paint.
Items you need:
• Touchup or color matched paint
• Compatible primer - I like Wurth Rustop
primer
• Organic cleaner - P21S Total Auto
Wash or Wurth Citrus Degreaser
• Solvent - Rubbing Alcohol or Prepsol
or Enamel Reducer
• 3M Imperial Hand Glaze
• Sanding Block 2000 grit
• Car wash
• 600 grit wet/dry sandpaper
• Round undyed wooden toothpicks
• Large lightweight cardboard boxes
(large shoe box or bigger)
• Several 100% cotton towels
• New Pencils with unused erasers
• Rubber glue
• Several heavy clean plastic cups
• Roll of quality paint masking tape
Paint chip repair is a learned skill and should
be practiced on an area of the car that is
not that visible. The hood and nose are two
areas that should be tackled last. Test all
cleaners or solvents on the paint prior to
usage. Try using the seam underneath the rocker
panels. Apply a little cleaner or solvent
to a cloth and rub the seam. If you do not
get any color on the rag, then the cleaner/solvent
should be safe for the paint. If you do get
color on the rag, then you may wish to consider
another solvent.
CHIP REPAIR STEPS:
1. At least 24 hours before
you want to start, use the rubber glue to
attach small 600 grit sandpaper circles (the
diameter of the eraser) onto several new pencils.
The eraser must be unused and flat on top.
2. Step #1: Wash the car
with a quality car wash and dry thoroughly.
3. Paint chips come in two
flavors. The worst case has exposed the bare
metal, while the less severe has left the
original primer intact. Clean the area thoroughly
with the P21S or Wurth Citrus degreaser. If
there is rust on the exposed metal, clean
off with the pencil eraser. Use a toothpick
to gently probe the area and make sure that
the edges of the chip are secure and not waiting
to fall off and destroy your work. This is
an optional step! If you do not feel comfortable
with sanding or your paint is one of the new
clear-coated finishes, you should jump to
step number 5. Take a new pencil/sandpaper
tool, dip into clean water and put a few drops
of water on the chip area. *SLIGHTLY* rough
up the chip and a small portion of the surrounding
paint. Lightly turning the pencil will rough
up an area the diameter of the eraser and
this should be more than enough. Keep the
roughed up area as small as possible, the
object is to give the new paint approximately
1 mm of old paint to "grab" around
the perimeter of the chip and not dig scratches.
4. Move onto the next chip
and repeat the above. Depending upon the amount
of time available, you may wish to tackle
10-20 chips at one time. Try to stay within
the area that may be covered by your box(es).
5. When finished sanding
all your chips you are tackling at this time
apply a small amount of Alcohol or Prepsol
or Enamel Reducer to a rag and wipe each chip
and surrounding area to remove any sanding
dust and grease/oils. Use additional solvent
and new area of the rag for each chip. Allow
to dry (these are highly volatile and will
evaporate quickly with no residue).
6. If the original primer
is intact, and "pencil sanding"
does not disturb the primer, then skip the
next step and go directly to painting (# 9)
7. Make sure that the chip
and surrounding area is clean. If not, reclean
with the Prepsol, Alcohol or Enamel Reducer.
Pour or spray a small amount of primer into
a clean plastic cup. Dip the point of a wooden
toothpick into the primer to get a thin coating
on the first 1-2 mm of the toothpick. If there
is a blob on the end, gently scrape it back
into the cup. Place the tip of the toothpick
against the center of the chip and allow capillary
action to literally flow a *THIN* coat of
the primer into the depression of the chip.
Move onto the next prepared chip. If you have
finished priming all your prepared chips before
two hours are up, cover with a box, taped
down with masking tape and go have a beer.
The key is to allow the first coat of primer
to dry at least two hours. Dispose of your
cup and start with a fresh cup and toothpick.
Apply another thin coat of primer to each
repair that needs primer. Priming is completed
when no metal is visible and the level of
the primer is *BELOW* the level of the surrounding
paint. This is important! Cover and allow
to dry for two hours or until dry.
8. Apply a small amount of
Alcohol or Prepsol or Enamel Reducer to a
rag and wipe the chip and surrounding area
to remove any sanding dust and grease/oils.
Allow to dry. Repeat for all the chips that
are on today's list of victims.
9. If you are using a touchup,
shake the bottle thoroughly. If you are using
color-matched paint, mix thoroughly and pour
a small amount into a clean plastic cup.
10. Dip the point of a new
toothpick into the paint to get a thin coating
on the first 1-2 mm of the toothpick. If there
is a blob on the end, gently scrape it back
into the bottle. Place the tip of the toothpick
against the center of the chip and allow capillary
action to literally flow the paint into the
depression of the chip. Repeat for each chip.
The key is not to use too much paint. Do not
redip the toothpick. Use only the amount that
will flow from one dip. Temptation to add
more paint with each application will be almost
overwhelming. Fight it!
11. Cover with your paint
box and allow to dry 2 hours and repeat 8-12
times till the depression is filled with paint
and bulges slightly upward and covers the
roughed up area with a thin coating of paint.
The first 2-3 coats may not completely hide
the primer. This is fine because you have
many more coats to go. Fight that urge!
12. The paint application
is completed when the new paint bulges slightly
upward (a fraction of a millimeter) and had
covered the roughed up area with a thin coat
of new paint. Allow the paint to dry for at
least a week.
13. The touchup paint has been applied
to the surface and allowed to dry for at least
1 week, and resembles a minute mound on the
flat plane of the existing paint. The object
is to remove the mound and make the surface
of the paint one continuous flat plane. The
Finesse Block offers the ability to gently
remove only the high spot of the repair. Unlike
sandpaper or polish on a rag, the five usable
sides of the block are flat and act like a
"wood plane" to remove only the
elevated areas of the repair. The 2000 grit
will not leave scratches.
14. Soak the Finesse Block
in clean water for 24 hours prior to use.
Put a small drop of car wash on the chip repair.
This acts as a lubricant for the sanding block.
Then gently "plane" the high spot
on the paint. I prefer to "plane"
in one direction (usually back to front -
drawing the block towards me). If the block
dries out, re-wet and continue use. When the
new and existing paints are blended (smoothed
to the flat plane) to your satisfaction, clean
the area using a quality car wash and lots
of water and then use a quality glaze to restore
the high gloss finish. I prefer 3M Imperial
Hand Glaze. Don't use a machine on your car,
as it deserves to be caressed by hand. Use
a machine on your Yugo or SO.
15. When applying either
a glaze or a wax, apply to your soft cotton
cloth or applicator pad (don't squirt the
stuff on the car) and work in one direction
only. Don't go around in circles like dear
old dad. Circles are many times the cause
of "swirl marks." A front-to-back,
back-to-front motion (the way the air flows
over the car) will help minimize swirl marks
or at least make them less visible. Buff out
with a soft cotton cloth. If it looks good,
wax with a quality hard wax and you are done.
16. Tip for applying wax.
If you are using a quality Carnauba based
wax, try applying it with your fingers instead
of a pad or cloth. Hold your fingers together
and use your fingertips as an applicator pad.
The tactile feedback from your fingers will
tell you when the wax has been worked into
the paint. If grit should lodge under your
fingers, you will know immediately and not
grind it into the paint. A pad will not allow
this tactile feedback and these devil grits
become sandpaper. A circular motion of the
pad will make a 360-degree swirl mark. All
marks on paint are most visible at a 90 degree
viewing angle. Thus the front to back marks
are most visible from the sides, whereas a
circle stands out from any viewing angle.
