Fresh Cedar - 9 months old

I have a deck that needs re-doing and a new fence that needs staining/sealing.  The deck is old wood that has been painted with a semi-solid stain that never seems to even last one year before needing to be re-done. (Don't know what to do - tired of going over it again every year!)

  I also have a new Cedar fence - shadowbox style - that is about 9 months old and hasn't grayed yet.  I want to stain/seal the fence and retain a beautiful cedar color.  However, I don't want to go through the same thing with the fence.   I have been reading your website commentaries and thought that, maybe, the 100 Pro Series TWP might be a good choice.  Because it has never been stained yet, I don't need to do anything in advance to the wood, right?  How would I know if it has a 'mill glaze' like I have read about on this site?  I did not build the fence.  Do I also have to 'seal' it after staining?  I thought there were products that did both.  Is that the right choice of product?
