Performance Coatings Inc. Penofin turned my deck black grew mildew after only a few months Ukiah California

I built a large deck in May of 2013 with brand new 5/4" cedar.  After allowing the wood to dry for several days, I applied Penofin blue label finish to it according to the directions on the back of the can.

It looked fine for the first couple of months, then I started to notice black vertical streaks on some of the vertical surfaces and  a large amount of mildew and mold growth.  It was as if this Penofin finish accelerated the mold and mildew growth!  I had to let it go through the winter due to running out of dry weather.  

In May of 2014, I tried power washing a small spot, the streaks lightened slightly but did not come off.  I could also tell that the power washing was raising the grain of the cedar, so I knew that would not resolve the problem. 

I applied a diluted bleach wash, let it sit for a few minutes, and rinsed well.  It looks a little lighter but the black vertical streaks still show On many of the vertical surfaces.  The diluted bleach basically killed the mold and mildew only, it did not get rid of the black vertical streaks.

The finish on the horizontal surfaces is almost non existent, keep in mind this is only one year old.  It is as if the sun or rain dissopates it.

The deck looks horrible after all of my hard work.  I have contacted Performance Coatings about it, but have not heard back as of yet.
