painting over oiled cedar timber

I have oiled cedar shutters in perfect condition but wish to paint them white. Can this be done and will the oil come through eventually?

Here's a previous discussion that may be helpful:

It appears that the secret to your success will be the use of a quality oil-based primer to prime/seal before painting. Cedar tends to be porous, so a couple coats of primer/sealer should seal the wood and block the potential for any bleed through. Read and follow manufacturer's instructions on labels. Shop at a quality paint store, not a big box.

The other unasked question is: Will paint stick to the oiled shutters?

What kind of oil? A non-drying oil?

I think an oil based stain blocker like Coverstain is needed before painting, but I would do a few cross cut adhesion spot tests first before proceeding to prime everything. Be sure of the primer adhesion - BEFORE priming everything.

The Coverstain should prevent any bleeding of the oil in terms of staining.

If adhesion is good, you may need to prime twice, as the cedar itself (not necessarily the oil) is prone to staining.
