The complexities of the various painting products and application methods can make it difficult for an amateur to understand why scrimping on a paint job is, ultimately, not a wise decision. So, this article has been started in an effort to diminish those complexities. If you are an auto body professional, an experienced hotrodder, or simply someone with good information on the realities of the "Cheapo" paint job, please feel free to add to this article.

==What's a "cheapo" paint job?==
 +
 
 +
===Cheapo application methods===
 +
====Rattle cans====
 +
 
 +
====Brushes and rollers====
 +
Often referred to as "powder puff" paint jobs because, historically, hotrodders actually applied paint with powder puffs designed to apply makeup.
 +
 
 +
These methods typically leave visible marks indicating that a cheapo method of paint application was used.
 +
 
 +
However, when viewing photos of paint jobs (in a magazine, on a website...etc.) there is a crucial factor to keep in mind: the brush or roller marks can be hidden when photographed. This could be done unintentionally, or with "selective" photography methods. Note the two photos below.

 +
To properly assess a paint job, you need to look at it in person.
 +
 
 +
===Discount paint franchises===
 +
====Maaco====
 +
While Maaco shops follow corporate Maaco guidelines, they are all independently owned and operated. So, depending on the management, your local Maaco shop may or may not do quality work.
 +
 
 +
However, in general, when speaking of Maaco, horror stories abound. ''(Research and expand on this specifically, and give examples and proof)''.

===Lacquer-based paint===
 +
====Dupli-Color====
 +
Dupli-Color is a lacquer paint product being sold by Sherwin Williams. It's marketed to the lower end of the skill and experience spectrum, as an easy-to-apply and inexpensive option for hobbyists.
 +
 
 +
Lacquers are the other "family" of paint products (the primary choice being enamels). While lacquer paints used to be commonly used, they have given way to the more modern enamels.
 +
 
 +
Lacquers literally "dry" -- the solvent evaporates. For this reason, lacquers will re-dissolve in their original solvent. By comparison, enamels "cure" by chemical reaction. If you apply lacquer thinner to a lacquer paint job, the paint will become a liquid again. Other solvents can have the same effect. Lacquers also have minimal UV protection. Lacquers are also "hot" when applied and often attack existing enamel paints, even well cured factory paint.
 +
 
 +
While you can paint over a lacquer paint job, the lacquer would likely be the weak part of the paint job.
 +
 
 +
Dupli-Color describes lacquer as "durable", and enamels as "very durable". This is, at best, a generous description, and at odds with what professionals are saying. Marketing aside, lacquer paints are not considered durable.
 +
 
 +
A Dupli-Color paint job would likely be fairly easy to apply, and look good when completed. However, it will not have the durability of more modern paint coatings.
 +
 
 +
You can't directly price compare a quart of Duplicolor to a quart of say, single stage traditional auto paint. Car paint must be "reduced" (like adding paint thinner) before spraying. At about a 50-50 ratio. Therefore a quart of such paint will make two quarts of usable paint. Duplicolor comes "ready to apply". Therefore we can say that it is only half a quart of paint and half reducer. Therefore you'd have to buy two to seemingly equal a quart of single stage paint. To carry it further, it's a fair estimate that you need around a gallon of paint to paint an average car. Plus a gallon of reducer, of course. Painters have noted that it takes quite a bit more lacquer to provide coverage equivalent to that the more usually used automotive paints. So the equivalent amount of Duplicolor needed may well be as much as sixteen quarts. If you want clear coat also that alters the equation a bit but Duplicolor still tends to come out as not such a bargain as it might first appear.
 +
 
 +
Some experimentation has led some to believe that what Duplicolor is selling in quart cans is basically identical to what they are selling in their spray cans as "touch up" paint. Just different packaging. Better results will always be obtained with a good spray gun but the curious can generally try the spray can versions to get a fair idea of what this paint is like without investing in any painting equipment.

 +
===Oil-based machine paint===
 +
====Rustoleum====
 +
====Pros====
 +
*Rustoleum can resist chalking and weathering almost as well as factory enamel paint if taken care of. Many people tend to judge Rustoleum by how it weathers on outdoor equipment and its other more usual applications. But no one buffs and waxes the wrought iron railings on their steps or outdoor oil tanks, so, yes, the paint tends to suffer.
 +
 
 +
*Until the early 1960's, many OEM's used alkyd enamels to paint their cars, which were quite similar to what Rustoleum has for sale today. Some import manufacturers continued using alkyd enamels into at least the 1980's. For example a 1981 Isuzu pickup will have a buck tag underhood clearly stating "alkyd enamel" as the OEM paint. Dupont's website has [http://pc.dupont.com/dpc/en/US/html/common/about/dr-history.html a small history section] that makes mention of their alkyd enamel automotive paint, "Dulux".
 +
 
 +
*Inexpensive, and widely available.
 +
 
 +
*Unlike a base coat-clear coat type spray paint job where things must be done within certain time frames, a Rustoleum roll and brush job can be started and stopped at the painter's convenience.
 +
 
 +
====Cons====
 +
*Rustoleum does not have UV protection. Its use will result in a paint job that will fade, chalk, and peel.
 +
 
 +
*Rustoleum frankly can not compare with a "catalyzed" or "two part" automotive paint for durability and hardness.
 +
 
 +
*There are no viable Rustoleum metallic paints for auto painting.
 +
 
 +
*Rustoleum enamels also lack the "depth" of color that many other types of paints have, though some people like the look as it compares well with many 1960's factory enamel paint jobs in appearance.
 +
 
 +
=====Application=====
 +
If you are considering using Rustoleum, it is highly recommended that you spend a few dollars on some to experiment with first. Take it home and apply it to something like a garden tractor or spare car hood in the same way you would to your car. Sand it, polish it, wax it, the whole thing. Then study it very closely and decide if this is something you indeed want on your car.
 +
 
 +
Rustoleum has been successfully applied by spraying, rolling, and foam brushing. The last two methods are accompanied by rather a lot of sanding. Also when rolling or brushing to get good results one should expect to put down up to ten VERY thin coats of paint. Decent results can be achieved by all three application methods.
