My client loves the Dark Oak exterior oil stain in PPG ProLuxe SRD RE and I can't get the non RE. I would have to travel out of state. I was told, on this forum, the RE version is crap. I have never used it. What can the homeowner expect if she insists on me using it? Will it not last as long? Will it require more time for me to apply? Will it fade quicker? Not seal the wood? This is for a house in NY. Full winters. Thanks in advance.
