					Automotive paint and the application systems used to apply the products have
changed significantly since the 1900s. In todays current automotive industry there are
four main types of paint which are: acrylic lacquer, acrylic enamel, acrylic urethane
and water based. Within the information below there will be the advantages and the
disadvantages of using such paint products and systems.

Acrylic lacquer based automotive paint systems came to prominence in the 1920s and
remained a popular choice for automotive paint applications up until the 1960s and is
still currently available in todays market. In most area of the industry the acrylic
lacquer paint has become illegal to use due to the high toxic vapours which are
present in its application within the car industry. The use of this particular paint was
popular because of its ease of application, and can be applied by an inexperienced
paint technician to a high standard, resending the use of costly qualified staff. Other
advantages with the acrylic lacquer paint are that the product had a high gloss finish
with relatively minimal refinishing. The acrylic lacquer paint is a relatively soft paint
and with this unfortunately the paint chips easily. Other disadvantages are that
constant exposure to UV and general cleaning chemicals reduces the paints
effectiveness making the paint a short lived paint job or repair. As stated above the use
of this paint system is not recommended because of its toxic vapours and gases.

The second of the three types of Car Paint systems available is enamel paints, these
particular car paints dry to a hard and more firmer shell than that of lacquer paints.
Most body shops that use these kinds of paints bake them on using large automotive
ovens or larger heat bays, where the cars are left for unto 6 hours at a time depending
on the paint thickness. Enamel paints are quite versatile and can be purchased in
aerosol form or for use with HVLP spray guns. Although automotive enamel paints
are tougher than lacquer paints they are not so easily sprayed on making them trickery
for the DIY enthusiasts to apply. With this in mind the enamel paints require a lot
more finishing work that the lacquer paint alternative. Some enamel course require a
clear coat, which is known as a two stage system, where as some other colours do not
require the use of a clear coat finish, these are known as a one stage system.

The third type of automotive paint system is Urethane paints. This type of automotive
paint is newer than enamel paints but more expensive and can be more difficult, On
the upside urethane paints lay down much easer than enamel paints and are similar to
lacquer paints in there ease of use while having the durability and toughness of
enamel paints. Urethane paints require three types of products in its make up: The
colour, a reducer ( an aid to thin the colour to the right viscosity in order to be used by
specific equipment like a spray gun in is application), and a catalyst which would be
used to decrease the products drying time in order for quick turn around. Once the
paint mixtures in all its parts are mixed, the product must be applied immediately and
all unused paint must be discarded safely for urethane paints are toxic. In most cases
to apply this type of paint system in a enclosed environment of a body shop for
example staff must where appropriate protective clothing such as a facemask, gloves,
coveralls and a respirator which would have to be air fed due to the concentrations of
contaminants in the immediate area, all these items should really be mandatory in the
application of Urethane paints. Just like the enamel paints urethane paints can be used
as a one stage or two stage system. The best use of urethane paint would be that of a
two stage system which most automotive body shops would recommend as it provides
an easy platform to lay the paint down and very minimal refinishing work after the
curing process. You can purchase urethane paints in aerosol form or in three parts in
order to be used within spray guns.

The last of the four types of paint systems available is that of the water based paint
Technology. Water based paint has brought us non toxic paint applications, these are
the most versatile paints out of all four listed above. They are able to be applied in
numerous ways, either to a primer, existing Car Paint Workor straight on to metal. In
most automotive industries where the use of graphics is required for example flames
to a car or viper stripes on a motorbike the use of water based paints is perfect for the
job. You can use this paint system to paint on graphics or to paint the entire vehicle.
Being non toxic water based paints are ideal for the budding DIY ers to use at home in
a garage, however it does require a clear coat or top coat of urethane to protect the
paint. Water based Paintis no doubt the best paint system of the auto paint industry
