I've been refinishing exterior wood with Thompson's water seal. I had 2
different methods for preparation:

1) Where I could remove the wood, I sanded it down to adios the grayed
wood.

2) On the unremovable gate, I used a mixture of tri-sodium phosphate
and bleach to remove as much gray as possible.

After application, the gate is markedly lighter than the rest of it. It
seems to my eye that I could add a red stain and that might match.

Any ideas on how to proceed?
