Painted metal which isn't sanded will be more prone to peel or flake off. If you're prepping metal that's already painted, you need to sand off and smooth. Use 120 grit sandpaper to get rid of any damaged paint. For painted metal where the paint is in good condition, use 240 grit sandpaper to roughen the surface.
When applying new metal paint, any old paint that is loose or is peeling away must be completely removed. Hand wire brushing, scraping, and sanding are a few manual methods for removing such paint deposits.

Yes, you should strip the paint before repainting, as the new paint will not adhere well to the old paint. Knowing which type to use and how the techniques work is the key to a successful, safe and satisfying de-staining job. Which type of product?
After cleaning, lightly sand the surface with fine-grit sandpaper (around 180–220 grit) to scuff up the glossy finish of the powder coating. This creates a texture that the primer can adhere to. Be careful not to sand too aggressively, as the goal is simply to roughen the surface, not to remove the coating entirely.
If you're painting metal that's already painted and in good condition, use 240 grit sandpaper to rough up the surface. This creates enough of a texture for the paint to stick to. If the old paint is flaking, remove it with a wire brush or sandpaper.

How Do I Paint Over Painted Walls? If the wall is in good condition and the paints are chemically the same (both latex, for instance), you have a few options when the new paint is the opposite shade of the old paint. You can use a primer to thoroughly cover the old color, then apply 1 or 2 coats of the new paint.
Minor Stains And Spots
If the existing paint is in good condition, with small spots, stains, and damage, and there is not much difference between the type and color of the new and old paint, you can repaint the walls without removing the whole paint.
New paint will not improve the adherence of the suspect old paint coating. Rather it is likely to make it slightly worse due to the stresses imparted as the new paint coating dries. Waterborne paints take a few days to develop full adhesion especially if applied in heavy coats in dubious weather.

Dimethyl sulfoxide (DMSO) has become more popular since it has a low level of toxicity, making it a safe replacement for methylene chloride and NMP. Opting for a safe active ingredient like DMSO or a manual paint stripping method will be far safer than risking NMP or methylene chloride.
Sanding is often a crucial step for ensuring that your surface is ready to be painted. If you don't have a properly sanded surface, paint may not adhere to certain items properly.
