its not anything complicated. if you never polished it before then it may pay for you to get a cut and polish initially, use a sponge similar to ones you wash you car with (not the same one of course), and apply a little polish on it, then spread over a section of paint, then keep doing it until all the paint is covered in a FINE film of polish. (you dont have to bog it on). then get a few old rags (old tshirts perfect) and buff it off contantly turning rag over so an unsoiled part of rag rubs the polish off. becasue you never done it before the first time will require a lot of effort (good workout!) to get polish off. your paint wil look heaps better after this. you only should CUT and polish it once as it is very abrasive.
but you need to seal it so then you get normal polish (merguirs, turtle wax etc) and do the whole process again, but because this polish is not abrasive like cut and polish, it will be much easier to buff off.
you wont know your car once you done this....just make sure you use plenty of rags when buffing off or it wont shine properly if you use only one rag over large sections of the car.
