Our car tire retreading paste contains laureth-7 and sodium laureth sulfate. It can form a protective film to prevent dirt, dust and other pollutants from adhering to the tire surface and keep the tire clean. Its use method is very simple: first wash off the dust and sand on the tire surface and keep it dry. Use a sponge to soak the product in the tire and wipe it, and finally wipe off the excess residue. It is also waterproof and dustproof, reducing dust adhesion.
