A test spot is done to determine what combination of polish, polishpads and technique will give you the best results when correcting a surface. A test spot is done in a small area before you start to fully detail the entire vehicle.
Why doing a test spot
When you are going to polish an entire vehicle, you might have a lot of work ahead of you. Using a combination of pads and polishes that give the best result in the shortest time will save you quite a bit of time and effort. Possible even the amount of product you need to use, which means you save on cost. This combination should be aimed at only saving time, because you can simply skip steps to save time, but mostly at finding the most efficient and effective combination of products and techniques.

When do you do a test spot
A test spot is done after fully cleaning and decontaminating the surface, but before you start to polish. You grab a few polishes, a few polish pads and start with the least aggressive combination to see how the perform. If you find that they don’t cut enough, or perform well enough, you change the product or the pads. You can also change the machine or the technique you are using. In the end you’ll have a combination that will save time while still getting you top results.
The benefit of a test spot
While doing a test spot you will learn and see that not every product always performs the same way on different surfaces. Some paint might be harder, of softer. Others are a bit more grabby or simply need much less correction. You’re experience in insight will grow and in time you will be able to make a better choice on what product would work best for your situation. Don’t just go in there with your most used polish and a random pad, but make an educated choice that will help you to get the best results.
