Shamelessly Ripped off from the SHO site

Materials
|
- Small bottle of the proper Toyota touch up paint and Toyota clear
coat, if needed (Toyota metallic finishes are clearcoat; a
non-metallic colors were not).
- DuPont PrepSol (available from autobody supply).
- Disposable touch-up microbrushes made by ProTouch (from an
autobody supply).
- 3M Perfect-It II Rubbing Compound, Fine Cut (from an autobody
supply).
- Lacquer thinner to keep brush clean.
- Wet-dry sandpaper: 1000 grit, 1500 grit, and 2000 grit (there is a
new product out that is an alternative to wet sanding for use in
auto touch ups - check it out at http://www.langka.com).

Procedure - Scratches
|
Use this procedure for long scratches and for large
chips.
- Use 1000 grit paper and wet-sand the scratch and the area around
it. Make sure to use lots of water when sanding. This keeps
scratching to a minimum.
- Use DuPont Prepsol to clean wax off before touch-up.
- Using microbrush and liberal amounts of paint, touch up the
full-length of the scratch. As soon as the paint drys (10 minutes)
do another coat. Repeat until you have done sufficient coats to have
built a small mound of paint over the length of the scratch.
- Let dry for 24 hours.
- Now wet-sand the touched up surface with 1500 grit wet sandpaper.
Sand in a front to rear motion since that's the direction the car is
painted with, hence: you're going with the grain of the paint. Sand
until you have eliminated the mound and any touchup paint outside of
the scratch.
- Clean area thoroughly and let dry.
- Take a clean microbrush and begin to apply the clearcoat to the
area. Don't be afraid to be liberal with it and don't try and keep
the clearcoat within the scratch area. Apply approximately 3-4
coats, again until there is a small mound. Let it set and completely
dry for 4-5 days.
- Now, wet sand with 2000 grit wet sand paper. You will begin to see
the clearcoated scratch blend into the rest of the paint - thus
disappearing. (It produces a very gratifying feeling!)

Procedure - Chips
|
You can use this abbreviated procedure to fix the many
small chips on the hood and front fascia.
- Use 1000 grit paper and wet-sand the scratch and the area around
it. Make sure to use lots of water when sanding. This keeps
scratching to a minimum.
- Use DuPont Prepsol to clean wax off before touch-up.
- Using microbrush and liberal amounts of paint, touch up the chip.
As soon as the paint drys (10 minutes) do another coat. Repeat until
you have done sufficient coats to have built a small mound of paint
over the expanse of the chip.
- Let dry for 24 hours.
- Wet sand with 2000 grit wet sand paper. You will begin to see the
touch-up paint blend into the rest of the paint - nearly
disappearing. The repairs are not noticable to passersby, and look
much better than the chips did.

Note
|
The clear coat on the flexible plastic parts doesn't rub
back as well as the rest of the paint, probably due to the flex agents
in the paint.. |
