Does polishing damage your car?
Every time you polish your car, some of the paint is removed, and so excessive polishing can remove too much paint. Incorrect technique can also lead to buffing through the paintwork or burning the paintwork, which might lead to the area needing repainting. But this is not always caused by improper technique, sometimes if there is damage to a panel such as a deep scratch, it might take bigger risks to correct it using paintwork correction. However, as the alternative to paintwork correction is repair-and-repaint, it is often worth taking the risk, as if successful it's a cheaper alternative, and if you go through the paintwork, the panel would have had to be repainted anyway.
