To paint a smooth surface, it is important to properly prepare the surface by cleaning it and sanding it to create a smooth and even texture. Use a high-quality primer to create a smooth base for the paint to adhere to. When applying the paint, use a high-quality brush or roller and apply thin, even coats to avoid drips and brush marks. Allow each coat to dry completely before applying the next one to achieve a smooth and flawless finish. **

Yes, you can paint over an already painted surface. However, it is important to properly prepare the surface before painting to ensure the new paint adheres well. This may involve cleaning the surface, sanding it lightly to create a rough texture for better adhesion, and applying a primer if needed. Additionally, choosing the right type of paint for the surface you are painting over can also help ensure a successful outcome. **

A good surface for oil paint is one that is sturdy and can withstand the weight and texture of the paint. Canvas is a popular choice for oil painting, as it provides a flexible and durable surface. Wood panels are also a good option, as they offer a solid and stable base for the paint. Additionally, primed surfaces such as acrylic-primed canvas or gessoed panels provide a smooth and absorbent surface for oil paint to adhere to. Ultimately, the best surface for oil paint is one that suits the artist's preference and painting style. **

Be sure to follow all safety precautions and test any solvent or paint remover on a small, inconspicuous area of the glass first to ensure it does not cause damage. **

No, paint does not only hold if the surface is sanded beforehand. While sanding can help create a rougher surface for the paint to adhere to, there are other methods to ensure paint adhesion. For example, using a primer specifically designed for the type of surface being painted can help the paint adhere without the need for sanding. Additionally, some paints are formulated to adhere to smooth surfaces without the need for sanding. Ultimately, the best method for ensuring paint adhesion will depend on the specific surface and type of paint being used. **
