looking awesome Budi, starting to get a shine after 2 coats.
Sorry I missed your question from April 25, just saw it.
Generally about 5 or 6 coats of extra gloss wudtone is enough.
Most of my projects I'm using Tru Oil clear coats and I tend to thin them down as its not self leveling to minimise the steaks. Some of the forum guys like Robin and Gav Turner are putting on 15-20 coats of TO to get a really glassy look.
You will know when there's enough top gloss coats, post some pics after the 4th or 5th coat ! Remember try and wait 48 hours between coats !
