About a year ago, I remodeled my front porch and used Garapa T&G with TWP Pecan stain. Thanks to all the advice I picked up from this site it turned out awesome. After about a year, most of the stain still looks perfect (porch is covered). The edges, however, get hit with some rain and sun so they are starting to fade.

So here comes the question - what do I need to do to keep the porch looking great and prevent the edges from turning gray? Reapply a coat of stain over the whole deck? Oxalic acid scrub and restain?

I'm kind of lost on what the best approach is and I'm afraid of doing more harm than good to it. If any of the experts want to weigh in on this, it would be greatly appreciated. Thanks again for all the advice posted on this site - the porch wouldn't have turned out nearly as good without it.

See pics below. It's hard to see the fading on the picture but the stain is definitely starting to wear out there.
