The genuine leather repair putty with added microspheres has the following advantages:

Excellent filling ability

Reduced shrinkage, reducing cracks and shrinkage in dry materials, making it easier to apply

High polishing performance and excellent polishing ability

Soft touch

low density

Good water resistance and low permeability

Low hardness, minimal impact on curing process parameters
