Hej alla polervänner vill dela med mig av Jesse O`Connors revew av Insta Cut # 15 med mkt tips o ideer hur man polerar...Utlåtandet är från Mars 2009.
iInsta Cut #15

-This is by far the most versatile polish that I’ve used to date. About 90% of all correction polishing can be achieved with this one polish alone. Most polishing products require that you polish a car in several phases; 4 for a great finish and 5 for perfection and here’s why. Take for example, the ceramic finish like on newer Ferraris, Mercedes, BMW and VW. They’re as hard as diamonds and polishing them is quite a task. The reason it’s so difficult is because you need something that’s aggressive enough to cut the paint to remove scratches and swirls, but there’s not a lot of products that can achieve this without marring the paint and basically giving it a “matt” finish. Now, in order to remove the matt finish created by the first pad and polish combo, you’ll need a pad and polish combo that’s aggressive enough to polish out the marring you’ve just induced, but mild enough not to cause more swirls/buffer trails. Then the process must be repeated, decreasing the pad and polish combo each time until all swirls and micro-marring are gone. This polishing system is extremely archaic and sacrifices a great deal of paint.

Insta Cut #15 can reduce polishing almost any car to just one phase and here’s how. Again, I’ll use a ceramic finish as an example. Starting with a foam cutting pad and #15, the polish should be spread evenly along the working area (about 2x2 feet) at 600 RPM (with a rotary buffer). This step is very important because just like any other polish, it can conglomerate, thus inducing scratches during the polishing process! No pressure is needed in this stage, as you don’t want the polish to begin diminishing immediately. Once evenly spread, about 25-30 pounds of pressure should be applied and at the same time, the buffer speed should be increased to 900 RPM. The speed of back and forth polishing movements should be about 1-2 inches per second. Most detailers tend to polish cars at high speeds (1,500-2,200) and swift passes, but with InstaFinish polishes high speeds are not necessary (though the manufacturer does suggest it).

Now in order for a diminishing polish to flash, or break down, it needs friction heat. Friction heat can be caused by high speeds, but can also be accomplished by slow speeds and more pressure. If you put your hands together in a “praying position” and rub them together slowly with almost no pressure, you’ll notice that there’s no heat being generated. Now, if you add a few pounds of pressure to that, while rubbing them at the same speed, you’ll most certainly notice a fluctuation in temperature. Now let your hands cool off and put them back together and rub them together quickly using almost no pressure like you did the first time... almost the same amount of heat was generated going fast as was when you were going slow with more pressure wasn’t there ? This is why I polish at low speeds! By doing this I control the polish and when it diminishes and I regulate how much it cuts, not the buffer. Furthermore, it gives you a much more controlled feeling and greatly reduces high-speed accidents.

Let’s get back to the polishing. Once I’ve made a couple of passes with the cutting pad and #15 (900 RPM with 25-30 lbs. pressure), I then reduce the amount of pressure because now my polish has started to flash. Therefore, I’ve already used most of its heavy cutting power, but now that it’s broken down a bit, I have medium cutting power! Then I make a couple of passes with that at 900 RPM using about 15-20 pounds of pressure for my medium-cut passes. After that, the polish should be well broken down, thus allowing you to clear up any fine marring or holograms by polishing it at either 900 or 600 RPM, using only the weight of the buffer as pressure. This is how polishing can be achieved with Insta Finish #15, with one step. Now, there may be a bit of micro-marring left on the paint, but this is not something that can usually be seen even in direct sunlight. It takes either a magnifying glass with LED lamps or a trained professional’s eye to see these marks. These can be removed with a finishing pad and #30 necessary.. this is the “5th phase” I was referring to.

For cars with softer paints, the same process can be completed either using a polishing or a finishing pad and #15, depending on how hard the paint is.
