*How Do I Buff Out High Performance Water Based Topcoat to a High Gloss?

There are several techniques by Jeff Jewitt of Homestead Finishing Products:

DRY BUFF WITH MIRKA ROYAL MICRO PAPER

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.

DRY/WET BUFF WITH ABRALON POLISHING DISCS

Start by dry sanding with Abralon 2000-grit, and then 4000-grit. Start slowly, monitor to see if buildup is occurring. A large sized table might take 5-25 sheets of paper.

If needed, lubricate by moistening with General Finishes Satin Finishing Wax, mineral spirits, or naphtha. Never use water as a lubricant.

If lubricated, one sheet of 1000-grit or 1500-grit should do the entire table.

BUFFING/POLISHING WITH PRESTA POLISHING KITS

Spray Presta polish on buffing pad stuff to lubricate the pad. Apply a quarter-sized dab of polish to sand one section. Spread with pad. Continue section by section. Mist buffing pad with Presta lubricating material when it gets too dry. You should be able to use a buffing pad on 10-20 tables before washing and reusing.
 
When done, mist entire surface with and buff with a micro-cloth to remove splatter

NOTE: Never wet sand a water-based finish.
