There might be certain situation in which it is advised to not polish a certain surface. This can be due to damage, time limit, thin surface or other factors. Knowing when not to polish might be as important as knowing when to polish.
Reasons to not polish
Sometimes polishing is not the advised course of action when trying to improve the finish of a surface. In these situations it is likely that polish will either create further damage, not have any effect or result in a dangerous situation. An example of these situations are:
|The paint thickness is to little||Continuing polishing will cause you to remove the clear coat, or the colored coat (depending on type of paintwork). When this coat is removed, it is very costly to re-apply a new layer.|
|You are working in the burning sun||Polishing now will result in polish drying up too quickly. The polish will not get the desired results and the dried up residue might create marks and spots that are difficult to remove. Unless you have a special polish that can be used on a hot panel, it is advised to not polish.|
|You only have a rough compound||Polishing with only a rough compound will result in an unfinished surface. After the compound step you need to refine the result with a less aggressive polish. Not doing this can give holograms, marks or a satin-look instead of a glossy finish.|
|It is raining and you can’t work indoors||Polishing in the rain will not give the desired result. Not only is rainwater contaminated, which will be rubbed around by the polishing pad, it will also dilute the polishing agent so much that the lubrication is greater then the polishing-effect. The polish will hardly do anything anymore.|
|You are ill||Working with machines always exposes you to some risks. Either to the object you are working, yourself or both. None of these should be exposes to increased risk because the operator is not capable of handling the machine correctly.|
|The surface is satin or matte||Satin or matte surfaces do not respond will to being polished. Polishing is designed to increase the overall look and to add gloss. Polishing a satin or matte finish will increase the level of gloss and remove the matte or satin look.|
|You have not clayed the surface||Claying or at least using a chemical cleaning product is very important. This step removes unwanted particles from the surface, unwanted particles that behave in an unknown way. Polishing with these unwanted particles can result in an unwanted or unexpected result, which is not likely to improve the overall look of the surface.|
|The surface is very rough and damaged||polishing the surface now might result in damaging your polish pad, your machine and maybe expose you to more risk then needed. The damaged and rough surface might also prevent the polish from doing what it should do. The end result will most likely be not satisfactory and could potentially even create more damage then before polishing.|
|When you’ve just polished your car last week||Remember that you remove a little bit of paint every time you polish a surface. It can be compared with sanding, but very, very light sanding. Polishing too often will remove more paint then needed and could remove the paint in a shorter time then wanted. In a few years you wont have any paint left to work with.|
|When you are short in time||Polishing takes time. Every panel needs a certain amount of time until the polish agent it fully broken down. You can speed up the movement or the speed on the machine, but it will not make a huge difference. Not taking the proper time to break down the polish could result in unwanted imperfections like holograms, buffer trails and microswirls.|
|When working on a very delicate surface||Using a machine polish could be to fast and to rough. Using a handpolish pad will give you more control. But in some cases, even this could be too much for a certain type of finish. Always judge what you are working with before you decide the right approach.|
|When the surface is covered in chemicals||Chemicals on the surface might be picked up by the polishing pad and get sling around. Not only can it hit you, it is also spread out over a larger area then wanted. Make sure the surface is clean before you start to polish.|
- Plexiglass/perspex is a very soft type of plastic (Polymethyl methacrylate) that is very rarely used. Just like glass or paintwork, it can suffer from surface imperfections. Swirls and scratches can be very visible because it is fully transparent....
- Marring is a superficial surface imperfection most commonly seen after claying. It is slightly similar to a combination between swirls and holograms....
- A Paint Thickness Gauge (often abbreviated to PTG, and also called a Paint Depth Gauge) is an electronic device that measures the distance between the body-panel and the sensor. This way you can measure the thickness of the paint. This gives you an indication of how much paint you have left to work with....
- Gelcoats are mostly found when working on boats and jetski's. It is a specified type of surface that is used in the process of making the shape of the object. A gelcoat is different then paint. It can be polished, clayed and protected, but slightly different then automobile paint....
- As with most products, it helps to know how to polish metal. In many cases you can only give a general guide, because even though some products can fall in the same catgory, they might still need a slightly different way of applying. Metal polish is one of those products....
- One of the best ways to take your car’s paintwork to the next level is to use a machine polisher to remove the Swirl marks and enhance the gloss by burnishing the finish. Polishing can be done by hand or by a dual action polisher. However, the rotary polisher represents the next step in machine polishing: a tool highly capable of fast correction but also capable of very high clarity, sharp and deep finishes....
