I had bought some samples of TWP 1500, and have some questions before purchasing a 5-gallon can. Would a darker stain, such as California Redwood or Pecan preserve the wood better? I have read somewhere that darker stains tend to have better UV filters.
Also, I will be applying the TWP 1500 to new redwood. Should I purchase a cleaner/brightener, or do I follow the instructions sheet on your website -- clean with household bleach and water? What are the advantages/disadvantages of either method?
