I found the text below via the search engine: have not posted here in a long time, so open to suggestions re the query below. Dave H had directly hit the topic in 2020. Regardless, always appreciate good advice ...
Dave H - a question please, from this older post: I now have in the mail, an engraved Yildiz pro star special .... and agree that the only fault in the (spectacular) wood I wish to correct is lack of pore filling; I can do a mirror sheen with oil, and have that on Perazzi, B25 and did those from bare wood - BUT, I'd prefer not to strip the Yildiz existing finish and start over. Could you advise me of your wet sanding technique? ie grit& paper grade, and presumably done wetted w. oil - and hand rubbed to fill?? TIA Garth
