Agreed. I’ve actually been practicing by turning down a spare piece of wood, finishing with ca then turning it down and doing it again etc.
What I have learnt is that it (I) was less effective on the stained wood compared to the natural piece, and it was due to my impatience of not letting it cure completely (I apply danish oil on the stained bit to give it more depth). The one I use says 20 mins drying but in fact I t takes a good 24 hours to cure fully before applying sanding sealer and then the ca finish. I’ve already noticed that it makes a massive difference.
