Wooden worktop fitting and oiling - help!!

[Yorkpud]

Hi, we have oiled our worktop on top and bottom 3 times and now the fitter is cutting it. So I presume we have to oil the ends etc. However, he says not to oil around the sink cutout as the sealant won't work. I don't understand this really as everywhere says to make sure cutouts are oiled the most. Or will I be able to oil this after fitting as I can probably access it under the sink??? I am really confused about this as all websites seem to say different things.

Anyone had a wood worktop and what did you do with the sink area and joins etc???

We oiled the ends and sealed with clear silicon no problems. This was for a standard drop in sink not undermount, not sure if that makes a difference

Thanks for that. The builder has sealed it all totally with PVA so I hope that's OK (some sites say it is some say it isn't!). Mine is a standard sink too.
