①The rubber scraper should be made of rubber with good oil resistance and solvent resistance (such as made of car tire rubber).
②When using, the force is even and moderate, do not bend the scraper due to strong force.
③ The blade of the scraper must be straight, without bending or tooth shape defects, otherwise it will affect the scraping quality of the putty, increase the grinding time and the number of scraping.
④After using the scraper, be sure to clean it with solvent, otherwise the putty will be adsorbed on the scraper, which will affect the next use. After using the horn scraper, it needs to be clamped with a flat splint to prevent its deformation.
