If our car has an impact and needs to be refinished, then before refinishing the paint, the master will level the putty where the paint must be refinished, so that the sprayed car paint will be smooth and smooth. So how to repair the cracks in car putty?

1. When there is a crack in the putty scraped by the car, if the crack position is serious, it is necessary to re-fill the putty in the original position. If it is often exposed to the sun or rained, or because the sheet metal foundation is not well polished, the putty will crack.

2. Try not to add other solvents for dilution when scraping putty, which may easily lead to paint cracking. Remember not to be too thick when scraping putty, and then brush it when the putty is completely dry. Once the putty is not completely dry, it will lead to poor adhesion of the paint and easy to crack again.
