Once it goes on, the material cures to a solid but flexible structure that sands and works beautifully. That lets you even out dents precisely and model damaged spots cleanly. The white pigment stops dark backgrounds from showing through and makes an even colour coat easy on light materials.\u003c\/p\u003e\n\u003ch3\u003eHow to apply it \u0026amp; best practices\u003c\/h3\u003e\n\u003cp\u003eBefore you fill, clean and degrease the leather thoroughly. You lay \u003cstrong\u003eFiller (White)\u003c\/strong\u003e down thin with a spatula, scalpel, brush or fine applicator tip. On deep damage, build it up in layers, each with a drying and sanding step in between. Once the surface is smooth and level, you match the colour with leather dye or Leather Fresh and finish by sealing with Top Coat. You can also thicken the filler with Thickener if you want more body.\u003c\/p\u003e\n\u003ch3\u003eResults, uses \u0026amp; benefits\u003c\/h3\u003e\n\u003cp\u003eAfter the work, the repaired area looks smooth, even and colour-neutral — an ideal base for a perfect finish. \u003cstrong\u003eFiller (White)\u003c\/strong\u003e works on white car seats, steering wheels, furniture, sneaker leather, boots, bags and light interior parts.
