Medium pile micro fibre roller heads suitable for interior emulsion paints and wood stains Can be used on smooth and semi-smooth surfaces  Versatile microfibre absorbs paint inside the fabric Loads smoothly and releases paint evenly throughout the stroke. During our own testing we found the micro fibre head to be perfect for use with both resins and gel coats releasing very little fluff.
