The wood is curly maple. I followed "the Creeks" advice and followed the suggested sanding regimen through hand sanding @ 220. Wood smooth as silk. Wiped it down with naptha, let dry and then applied a coat of Transtint dye. One coat of BLO ,and one coat of Seal Coat at something less than full strength. So far so good. Three coats of Rockhard at approximately 90/10 and now I see imperfections that look like pimples/dimples. I sanded the first coat of Rockhard with 220 premium on a Festool 125. I wet hand sanded subsequent coats with 400 w/d and the finish is smooth. What should/could I have done better to not have dimples/pimples? Short of returning to square one is there a fix?
