If you are planning to do paint correction yourself then you have to invest a lot of time in learning how this whole process works. I don't know what level of experience you have in this field but paint correction, when done by a professional, can take anywhere between 6-12 hours for your car depending upon the condition of the paint and also upon the type of result you are looking for. The process involves you using a buffing machine (rotary or orbital etc) and using some chemicals in order to 'skim' some of the clear coat around the scratches in order to level it with the paint around it. A Makita buffer costs like AED900 and an orbital buffer like the FLEX VRG3401 costs AED1500. Chemicals, such as the compound, polish and finishing polish can cost around AED1000 or less if you are lucky to find them in small 250ml bottles. But there is a lot of science (and marketing) behind the chemicals as each of them is different in the amount of 'cut' it provides and the type of finish it leaves on the paint. Additionally, you have to be mindful and knowledgeable about the type of paint that you are working on because some paints, like most Japanese cars, is soft so you have to do a test spot and test which chemical works best. 'Least aggressive' is the approach that you have to use in order to do a test spot. Man, there is so much more on this that I can go on and on But I will leave you with a good resource to do all your reading etc .... autogeek.net ... that is where I learned how to correct paint and then I tried it out on my cars. Let me know if you need additional pointers ...
