Bleeding Of New Cedar Clapboards ?

Hello:
Will be having new horizontal Cedar clapboards put up in a few weeks. They will be pre-primed, front and back.
Trying to get a bit of a heads up regarding the painting of them afterwards.
The contractor said that "sometimes" there is a bit of bleeding from the Cedar clapboards, thru the primer, once they are up. He also suggested waiting a few weeks before any painting.
Questions:
a. If so, what should be done about this prior to painting ?
b. Or, will the paint (probably 2 coats of latex) cover up any bleeding "for all time" ?
c. No matter what is done, is it likely to continue to bleed again (thru the new paint) ?
Any thoughts on all of this would be most appreciated.
Thanks, Bob

Nothing can be done but wait like your guy said.

No. Your guy has done you a favor by telling you to wait. He is familiar with the material and has seen the problem before. You would like to have better material but we no longer live in that world.

Predictions can be hard to make. How about....maybe? In any case, no paint last forever. When you get ready to repaint you can sand and prime those areas before painting the rest.
