Hi John, If it works as a finish, which it looks to do, don't change it.. I went to using oil for sometime, but as with most of the finishes I still have, some which are old, the oil which I was using, I found would darken the wood to much, maybe because in changing it's container, it looks black.. I've just got the microcrytalline wax and have thinned down the cellulose s/s I had and gone to using them now, I'd also been using friction polish, but that would fade an go flat, but then finishing can be as long as turning, so a rushed finish maybe the answer there. I've yet to get a buffing system, it's the cost against, will it work well.
John, (tbht) I'll add Goncalo Alves, to your Iroko, you don't get real shaving and it's very dusty, you only notice it by a layer on every surface and most is from turning, that's with the microclean on...
