After the putty is scraped on the 2k paint surface or OEM paint (original paint), the putty mark appears after the topcoat process.

Reason:

(1) Use inferior putty.

(2) Improper mixing ratio of 2K primer in poor use.

(3) Scrape putty before the 2K paint is completely dry.

Prevention:

(1) The use of good quality putty can avoid problems such as the appearance of soil marks and loss of light.

(2) If you need to make up the putty using high-quality 2K paint film, it is recommended to heat and dry it before making up the putty.

Remedy:

(1) It can be polished with P1500 sandpaper, and then remedied by the waxing process.

(2) In serious cases, re-spray after grinding.
