To make the product bright and beautiful, you can use liquid polishing wax and wipe it evenly with a soft cloth to achieve the goal.
3. Adhesion If the product is accidentally damaged, you can use IPS adhesive glue/adhesive methylene chloride type adhesive or quick-drying agent to bond it.
4. Polishing If the product is scratched or the surface wear is not very serious, you can try to use a polishing machine (or car waxer) to install a cloth wheel, dip a proper amount of liquid polishing wax, and evenly polish it to improve.
