• Stir evenly before use, and the remaining atomic ash that has been scraped cannot be poured back into the original tank;
• Before scraping, it is necessary to mix atomic ash and curing agent in proportion, mix them evenly, and avoid cracking or softening;
• Curing agents are flammable, explosive, and irritating to the skin. Avoid direct contact;
• Atomic ash should not be too thick in a single application, and deep pits should be scraped and coated layer by layer;
• It is prohibited to directly spray the topcoat onto the putty to avoid affecting the gloss of the topcoat.

• The main component isocyanates are prone to react and deteriorate with moisture in the air;
• Additives (inhibitors/promoters) affect product stability;
• The formula needs to be adjusted according to the environmental climate ratio;
• It needs to be stored dry and sensitive to climate;
• Poor quality packaging can reduce product quality.
