If the budget is limited and the repair scope is small, 1K paint is an affordable choice. If the budget is sufficient and the paint film performance requirements are high, it is recommended to choose 2K paint. Although the price is higher, its excellent durability is worth the investment.

● 1K color paint: The mixing ratio of 1K color paint and thinner is usually 4:1, that is, 4 parts of 1K color paint to 1 part of thinner. ● 1K clearcoat: The mixing ratio of 1K clearcoat and thinner is usually 2:1, that is, 2 parts of 1K clearcoat to 1 part of thinner.

The "2K" in 2K auto paint stands for "two-component", which means that this paint consists of two separate ingredients: the main ingredient (base paint) and the curing agent. These two ingredients need to be mixed before use and cured through chemical reactions to form a hard and durable paint film.

Primers suitable for 2k car paint include: epoxy primer, polyurethane primer, acid-cured primer, acrylic primer, etc. Primer is a coating specially used to form an initial coating on the surface of a substrate. Its main function is to provide good adhesion and provide a flat and smooth base surface.

Primer: usually between 20 and 40 microns, the main function is to provide adhesion and rust protection. Intermediate paint: 30 and 50 microns, the main function is to provide color and thickness. Topcoat: 40 and 60 microns, the main function is to provide the final gloss and aesthetic effect.

● 1K car paint: The label will be marked as "1K" or "single-component paint", and no curing agent needs to be added. ● 2K car paint: The label will be marked as "2K" or "two-component paint", which needs to be mixed with curing agent in proportion.

The "1K" in 1k automotive paint stands for "one-component", which means that this paint does not require mixing hardeners or other ingredients before use. 1k car paint is a pre-mixed paint that can be used right out of the can, which greatly facilitates construction and application.
