As an automotive care specialist, I've spent years studying and working with various cleaning and maintenance products, including rubbing alcohol, which is also known as isopropyl alcohol. The application of any substance to a vehicle's paint requires a careful understanding of its chemical composition and potential effects.

Rubbing alcohol is a versatile solvent that's commonly used in a variety of settings, from medical applications to cleaning tasks. It's composed of isopropanol, which is effective at dissolving many substances. However, when it comes to car paint, the use of isopropyl alcohol must be approached with caution.

Isopropyl alcohol is NOT recommended for freshly painted finishes. Freshly applied paint is particularly susceptible to damage from solvents, as the paint may not have fully cured and is more vulnerable to chemical reactions. Full-strength isopropyl alcohol can dissolve the paint, leading to discoloration, streaking, or even peeling. This is why it's crucial to avoid using it directly on the paint without dilution or on untested surfaces.

On the other hand, when diluted accordingly, isopropyl alcohol can be a useful tool in the preparation of surfaces for painting, glass or wheel coatings. The key is to find the right balance in dilution to ensure that the solvent properties of the alcohol are harnessed without causing harm to the surface. This is typically done by mixing it with water in a controlled ratio, which can vary depending on the specific task at hand.

It's also worth noting that the type of paint and the vehicle's finish can influence how isopropyl alcohol interacts with the surface. For instance, some modern automotive paints have additives that make them more resistant to solvents, while others may be more sensitive. Always test a small, inconspicuous area before applying any cleaning product to the entire surface.

In summary, while isopropyl alcohol can be damaging to car paint if used improperly, it can also be a beneficial prep solution when used correctly. It's essential to understand the product, the surface you're working with, and to always proceed with caution.
