Hi Sat, There are two types of polishers available - Dual action and Rotary. I think Italia-Linea has a thread somewhere here. Found it - http://www.teamfiat.co.in/do-yourse...ment-your-car-rotary-vs-orbital-polisher.html Dual action polishers are gentler in their action and hence easier on the paint. They are also a little slower than the rotary. They are the best choice for a DIY detailer because it is difficult to cause a paint damage using them and with the right choice of pads and polishes, it is still possible to get very good results. Only gripe is that you'll take more time, but then it's mostly your own car, so you are not in a hurry to finish off and move on to the next car. Unfortunately DA polishers are not commonly available in India. You'll need to import one. Some good makes are - Porter Cable - Made in USA, so only available in 110V, 60 Hz. If we have to use it, we need a step down transformer. A lightweight machine, so nice to use. Griots Garage - Same as above almost, though some people say that it's slightly more effective than the PC. Kestrel DAS-6 - available in two versions. DAS-6 and DAS-6 PRO. The PRO version is the one to go for. This one is a German machine. European equivalent to the PC. More importantly, runs on 220V, 50 Hz. supply. Meguiar's G220 - Similar to the Kestrel, though I believe the Kestrel is somewhat lighter than the Meg's machine. Flex VRG - Amazingly light machine and reportedly it's a joy to work with. It has a forced rotation mechanism, which improves it's effectiveness and actually places it between a DA and a rotary polisher. Highly expensive. Rupes Bigfoot - Again very light and effective. Also very expensive. Rotary polishers are faster and more aggressive in nature. The key to successfully operating a rotary on the paint is to not apply much pressure, keep the pad lubricated and keep the polisher moving. It also takes some practice to smoothen out the movements. It is a better choice for a pro detailer because they can get the work done faster and thus in theory can do more cars per day or per month, thus earning more. Rotary makes - Skil Polisher - Chinese brand taken over by Bosch. Cheapest one available in India and does the job, though has limitations on speed variations etc. It is also a little bulky and heavy. Dewalt - A very good polisher with nice speed control, lighter than Skil but also more expensive. AEG - Similar to Dewalt, but the speed control on the Dewalt is reportedly much better. Makita - Most expensive of the lot. They have a good name, but I don't have much info on the machines. Bosch - It's in the same league as AEG/Dewalt I think. When it comes to pads, you have the following choices - Wool pads - These can be natural wool or synthetic wool. The ones which come with polishers by default are synthetic wool pads. They are the most aggressive, and it's best to ditch them at least in the beginning till you really need to do serious paint correction. They are also large in diameter (8" is standard), making them even more unsafe for the paint. They can best be left for the professionals who know how to handle them with a rotary polisher. Foam pads - Most popular ones. These come in various foam grades, and are termed as Cutting pads, polishing pads or finishing pads based on their density and softness / hardness. Most of the companies also follow a colour code for them. So generally an orange or yellow pad will be a cutting pad whereas a white pad will be a polishing pad. A black / red pad is generally used for finishing purpose or even for waxing. However, beware that this is not the case with all the manufacturers and some of them do follow a slightly different colour code too. Microfiber pads - These are essentially foam pads covered with microfiber. These provide a little more 'cut' than the foam pad and can be used for paint correction sometimes. You also need a good backing plate for the pads. Normally, the polishers either come with a default backing plate or they don't. Even if they do come with a backing plate, the default BP is of crap quality, and they are also of 7" size, so can take only 8" pads. What you need is good 5" backing plate which is strong yet flexible. These will allow you to use either 5.5" or 6" pads thus giving you better control and access to the contours on the paint. Some Pro detailers also use 3" backing plate with 4" pads to reach complicated areas on the car paint. Coming to your specific question, mild polishing will most probably not remove swirls if the vehicle is heavily swirled. The so called mild polishes are normally designed to remove the holograms and haze left on the paint by the harder compounds. So for very mild swirling, it will probably work. Also, when using a pad / polish combination, always start with the least aggressive combination and move up as / if required. So as an example, you can start with a white pad and M205 and see how it works. If you feel that is not sufficient, try the same polish on an orange pad. If even then things are not improving, then you go to the orange pad / M105 combination.
