On the black oak laminate I spraid the KTM-9 surface prep spray but used a regular water lacquer - Daft I think? The surface prep worked well, but trying to get piano gloss on black is a challenge. Very senstive to overspary. The results were ok for a first attempt, but not as good as I hoped for. Can't blame the KTM product. But it is an expensive product compared to those available from Rockler, etc.
