    Hi, am new to the world of customisation and I have some questions about sanding:-

    Whats the difference between wet and dry sanding ? Which is better?
    When sanding, what are the types of grit recommended for a repaint? A 1,000 or 2,000 grit?
    Why do people sand starting from a lower grit to a higher one? or on an existing paint (spray) job

    Any help or links is much appreciated.

    I use a very fine grit sanding paper overall. I don't why, but I sand wet too..works great.

    differences in wet sanding and regular sanding is exactly what it sounds like. One is wet the other isn't. Recommended sanding is starting off with something like... 120 or finer for initial sanding for the paint to adhere to the plastic. Once the paint is on the reason we painters like to wet sand the final coats is 1) it helps the next layer of paint to adhere 2) if there are imperfections in the paint they can be sanded out, and depending on what gets removed while trying to fix a run or blemish in the paint, minor touch ups will be all that is needed, and 3) when sprayed the paint will sometimes leave a textured surface, and the very very fine grit papers (the papers that feel like paper from a notebook or news paper, incredibly fine) will help to more or less buff that textured surface smooth, and when the clear coat is properly applied will give you a factory automotive looking finish. Hope this helps you out my friend, and good luck to ya.
