How the Pros Avoid These Common Paint Mistakes

If you’ve never painted a car before, you might assume that it’s
much like using a sprayer on an exterior wall of your home. But
painting cars is far more complicated, and it’s easier to botch
the final result. Never try a DIY approach to painting your own car—you’ll
only end up taking it to an
auto paint shop when you see your results. Here’s a look at how the professionals
handle car paint jobs.

How the Handprints

It’s very
easy to inadvertently contaminate a panel. When this happens, the end result can reveal handprints. Handprints may
first appear through the paint as small blisters. Within a month or two,
you might start to see the actual print rising to the surface. This happens
when the painter places a hand against the panel while prepping it, and
doesn’t clean the area afterward. Salt and oil from the skin stick
to the panel, leaving the handprint. To avoid this problem, professionals
at an auto paint shop can wear gloves to prevent the transfer of contaminants.
Alternatively, they can thoroughly clean the panel after sanding it.

How the Pros Avoid Blisters

Paint blisters are unsightly, but easily prevented with the right prep
work. Experienced technicians understand the importance of washing the
car with a wax and grease remover. Amateurs often skip this step, reasoning
that they’re just going to sand the panel anyway. The problem with
this is that the sanding tool gets coated in wax and grease. As the metal
is sanded, the heat generated by the tool melts the wax and grease, and
melds it directly into the metal surface. The undesirable effects might
not be noticed right away, but the paint blister will definitely make
an appearance later on. Pros avoid this simply by giving the car a thorough
scrubbing with a degreaser before getting started with sanding.
