Wood Turner's Finish does not need wet sanding. If feel the need for more sheen, dry polish with Merka Abralon 1500-4000 grit or Micro Mesh 4000-8000.
There are several techniques by Jeff Jewitt of Homestead Finishing Products:
Using Mirka Royal Micro sandpaper, always start with 1500-grit sandpaper. Begin with a small area, make 2-3 passes, then evaluate results. Go to a heavier grit if surface irregularities are not fully removed. Finish with 1500-grit paper.
Exterior 450 Topcoat is a tintable clear-drying low VOC finish suitable for vertical exterior surfaces, such as fences, patio furniture, garage doors and entrance doors. It is not recommended as a deck finish.
