I'm wondering if there are any places that will mix you up a small quantity
of metallic car paint i.e. 100ml or less. I'm looking for perfect match
paint to touch up a few areas of my car, namely the dash panel, alloy wheels
and bodywork. At this point I think I should add a warning about they type
of car air freshener that contains a small bottle of pefume and clips onto
an air vent. Mine somehow managed to leak a 'dribble' of perfume which has
dissolved a streak of paint as it's run down from the drivers side air vent
on my Mondeo. Very annoying, Grrrrrr. I'm hoping that if I can obtain a
good match, I can rub it down and airbrush it over, but obviously only need
a small quantity.

You won't get perfect matching paint especially in metallic by simply
reducing the paint formulae which is what will happen when attempting
to reduce the quantity down to 100ml.
1000 Millilitres = one Litre
500 Millilitres = half Litre
100 Millilitres = one eighth of a Litre
Mixing a quantity as low as 100ml would prove quite difficult because
the mixing ratios won't go down that far and they tend to be measured
by weight in Grammes not Mls.
The paint mixing formulae is designed to be accurate on larger amounts
which is why paint is usually mixed and supplied in litre form although
some outlets will mix as little as half a litre.
I don't know of any paint mixing factors that can mix is smaller
quantities.
The formula is far less accurate on a half litre mix than it would be on
a litre or more so 100ml would be impossible to match accurately.
The only way to guarantee an exact match is to have the paint mixed and
applied at a car body shop who have the necessary equipment to apply it
by spraygun using the correct viscosity air pressure and temperature.
You could actually use the same batch of paint the vehicle was originally
painted in and it would still not match accurately unless it was applied
the exactly the same way.
Metallic in particular can only be accurately matched successfully
professionally because you can alter the colour slightly from light
to dark simply by increasing or reducing air pressure. You obviously
cannot do this with an aerosol but could possibly using an air brush to
some extent.
Because metallics are generally basecoats (a matt or flat finish) they
need a protection coat this is called the lacquer coat which provides
the shine and durability.

Those touch up bottles with a brush in the cap? You could thin it down for
spraying.
Steve. What do you prime plastic with to give paint a good key? Or is
is sufficient to just give it a light rub down with fine wet and dry?

In the trade you would use "panel wipe" which is a solvent cleanser to
de-grease the panel or bumper first and then rub rub with a coarse (red)
scotch-cloth to provide a key, then use a special plastic promotional
primer to spray the plastic or rubber composition bumpers to form a key
for further substrates. You can use wet-or-dry but it's not very
effective unless it's really a coarse grade which is why scotch-cloths
are used instead. You can however use a kitchen pan scourer though.
The interior dash does not necessarily need to stand up to the same wear
and tear as a bumper would so the chances are an ordinary primer will
stand up very well even to the high temperatures reached inside the car
during hot summer days.
Clean, scotch and just paintaway :)
Thanks Steve. I might give it a try
> 1000 Millilitres = one Litre
> 500 Millilitres = half Litre
> 100 Millilitres = one eighth of a Litre
Your calculator needs a smak, i make that a 1/10th of a litre.

Well it was near enough :)
