NT-311 FADE OUT THINNER – is a special solvent (also known as a blender) used in the automotive refinishing industry to mix paint to create a smooth transition between new and existing paint. It helps “fade out” these edges of the repair area, making the transition almost invisible. This process is particularly important for spot repairs and touch-ups where achieving a flawless transition is needed. Typically, one uses it with basecoats and clear coats to create a seamless finish.
