A
Paint Primer for Consumers
Thinking
of getting your car painted?
The
experts answer your questions: An interview with Dennis Beeler,
instructor, Auto-Body Excellence Centre, Southern Alberta Institute
of Technology, Calgary and Bob Hamilton, regional leader, DuPont
Canada, for Western Canada.
Question:
Is a paint job a wise investment if you're going to sell your car?
Answer:
People who know cars often like to be able to see what they're getting.
New paint could hide rust or corrosion -- buyers may prefer to see
the original finish. On the other hand, some buyers are impressed
because a repainted vehicle looks good -- it's a strong selling
point. Then there's the matter of economics. A good paint job will
cost about $2,000. Will you recoup the $2,000 in the selling price?
Question:
Is a paint job a wise investment if you're going to keep your car?
Answer:
If your car's body has chips or scratches and is showing signs of
wear, a paint job is a wise investment. The paint will not only
take years off your car's appearance, it will protect it from rust
and corrosion.
Question:
Should I change my car's color?
Answer:
Changing the color increases the cost of the paint job because areas
such as the inside of your trunk need to be painted. And if scratches
or chips occur, the old paint color may be exposed.
Question:
Can new paints be applied over the existing paint? Answer: In most
cases, yes. The best base finish for applying paint is the original.
If your car has an acrylic lacquer finish, however, it should be
removed before repainting. Since acrylic lacquers don't contract
and expand like other finishes, they tend to crack, damaging the
new finish. Lacquers are no longer available due to their high solvent
content and tightened environmental regulations.
Question:
How do I know I'm getting a fair price?
Answer:
Generally speaking, you get what you pay for. For example, a single-stage
paint is cheaper than a base coat /clear coat combination, but is
less durable. Additional prep and detail work is also required to
apply a two-stage finish. Be sure each bid reflects the same caliber
of preparation.
Question:
What's the difference in single-stage and multi-stage paints?
What
about different types of clear coats?
Answer:
A single-stage paint is less than a base coat only. The two-stage
process combines a base coat and a clear coat, providing a more
durable finish with a deeper, longer lasting shine.
Question:
What about warranty? Answer: Most paint companies certify autobody
technicians to apply their products. The warranty may be directly
with the paint company or with the body shop. Most paint companies
stand behind their products, if they are applied properly. Most
body shops guarantee workmanship for a specified period. The vehicle's
condition, however, may affect the length of warranty. If, for example,
the vehicle is rusty, the warranty is likely be shorter than if
it were not.
Question:
If I'm only getting part of my vehicle repainted, will the paint
match?
Answer:
Generally speaking, yes. To reduce the possibility of noticing this
difference, most painters feather the new color with the existing
color on the adjacent panels. This process is called blending and
should be specified on the work order.
Question:
How do new paints protect the environment and affect costs?
Answer:
High solids paints contain less solvent, and therefore less VOCs,
than acrylic lacquers. The new high volume, low pressure paint guns
that are used to apply high solid paints spread the product more
efficiently than traditional spray guns, therefore emitting fewer
VOC's to the atmosphere. Since the guns produce a softer spray than
traditional spray guns, more paint lands on the vehicle, eliminating
over spray and allowing less solvent and contaminants into the atmosphere.
Question:
I'm a vintage car owner. I understand vintage paints will not be
available. What do I do?
Answer:
Some of the older paints are no longer going to be available because
they contain volatile organic compounds (solvents) that evaporate
and exhaust into the atmosphere, depleting the ozone layer. The
exact colors of the vintage paints, however, are available with
current base coat/clear coat finishes.
Question:
How will my car be protected against corrosion?
Answer:
Part of the refinishing process includes replicating the factory
corrosion protection processes. An E-coat, the factory protective
coating, is applied to the bare metal prior to priming.
Question:
How should I care for my new paint finish?
Answer:
Keep it clean. Most of today's paint finishes are base coat/ clear
coat finishes that don't need to be waxed. Dry your vehicle thoroughly
when washing it in sub-zero temperatures. But beware: if your vehicle
is very dirty and you use a brush to wash it, the dirt can get onto
the brush and cause scratches in the finish. Try using a pressure
hose to remove the heavy soil before using a brush. Some waxes,
such as silicon based or sealer waxes, seal the car's finish so
that the finish can't contract and expand adequately, causing the
finish to crack and allow moisture to enter. Wax build-up also yellows
the finish, giving it a hazy appearance. Although new paint finishes
do not require wax, those who wish to wax should use a high quality
natural wax.
