2. Primer
  Do I need a primer?
Primer is recommended if you are doing repair work, going direct to metal, or are changing from one color to another (painting over one solid color,
such as a grey primer, will give you a more even finished paint). Yes, you can use an aerosol primer. However, use a quality automotive primer to
assure compatibility. Sem products, Spray Max, and House of Kolor are very good products used by professional automotive shops. The aerosol
primers are listed below with their item numbers click on the link to read more about them.

3. Paint
  What's the difference between a 1K Base coat paint or a 2K Single Stage paint?

Spray Max 1K (containing one product) is a base coat paint. It has more coverage than the 2K aerosol and does not have to be activated, so it can be used again and again for touch ups until the can is empty. It must be clear coated. Using a clear coat gives the added benefit of protection against the sun's UV rays, which causes fading. The 1K basecoat/clear coat system has the added benefit of less orange peel. Also, in the event scratches or repairs need to be made, the clear coat can be color sanded. We suggest using the Spray Max 2K Glamour Clear Coat. This gives a high gloss clearcoat with a durable finish.

Spray Max 2K Single Stage (all necessary products in one can, the paint and activator/hardener, clear and reducer) is an activated paint. Once the can is activated it must be used within 12 hours. One of the advantages to the 2K aerosol is no separate clear coat is needed, saving you that extra step. However, the 1K base coat, since it does have the extra layer of 2K clearcoat, will hold up longer.

Which paint is best for you? The base coat/clear coat method will give you a better, more durable finish. However, each project is different, consider carefully he needs and use of your project, consider the characteristics of the 1K and 2K paint and then make your choice.
4. How much paint do I need?

How much paint do I need?

Our most often asked question is, 'How much product do I need to spray my project?' This is always a difficult one to answer, since each paint
formula is different. Here are a few things to keep in mind when trying to decide how much to order. In most cases, you will need more product
for silvers, yellows, oranges, and some reds since they do not have as much pigment in the formula as the darker colors like blacks, greys, blues,
and darker greens. Back ground color is another element that needs to be considered. If the same color is being painted over an existing color not
as much new paint will be needed as compared to changing drastically from one color to another, for example a red to a white. Another factor in
determining coverage is technique, experienced painters generally need less paint, since they have fewer errors to correct (for example, sanding
out a run and then applying a repair coat over the area).
A starting estimate is one aerosol spray can per 3x3 to a 3x5 area.

5. How long should I wait between paint coats?

How long should I wait between paint coats?

The wait time (flash time) between coats of paint, is about 10 to 20 minutes at 70°F, if it is high humidity or cool you will want to wait the longer time.
For every fifteen degree drop in temperature you need to double the wait time. (Not recommended to spray 2K products below 60◦.)

6. How long after the paint should I wait to clear coat? What is the wait time between clear coat layers?

How long after painting should I wait before clear coating? What is the wait time between clear coat layers?

For the clear coat, you should wait at least 45 minutes before spraying the clearcoat over the paint, but wait no longer than 8 hours.
Between coats of clear the time varies according to temperature, humidity, and air flow. The best test is the "string" test.

1. Find an area on masking tape near the wettest point of the sprayed clear.
2. Press your finger into the clear on the tape and lift about one inch.
3. Look for fine strands of clear is not ready for the second coat.
4. If the spot strings the clear is not ready for the second coat.
5. It is ready when the clear is tacky but not stringing.

7. How do I prevent the nozzle from clogging and spitting?

How do I prevent the nozzle from clogging and spitting?

Watch You Tube Video - On Clearing the Spray Nozzle

If the nozzle does clog and you have another aerosol with the same product you can switch the nozzle out with the unused nozzle. Then clean it and replace it.
It is important to clear/clean the nozzle after each layer. Don't allow the product to dry on the nozzle.

8. What is a standard color and a variant color?

What is a standard color and a variant color?

Each paint code formula has a standard version, which is the most common formula. However, there are variations of most paint code formulas.
This occurs at the factory. Unfortunately, variant information is not on the vehicle. The only way to determine if your vehicle is a variant color is
by color matching. We mix the standard formula unless we have received a sample to match. If you believe your vehicle may be a variant you
will need to send us a sample piece off of the vehicle to match. Send to 66 Auto Color, 3720 E. 20th St., Joplin, MO 64801 with all of your
contact information and vehicle paint code information.
