Nanolex Si3D Application Block

Nanolex Si3D Application Block

Nanolex Si3D Application Block is better than suede cloths for applying thin, even layers of ceramic sealant, without being fiddly to use. This firm foam block has a softer, open cell foam topping. This combination provides a better grip and a flat surface for even sealant application, right up to the edges of trim and into tight corners.
