Paul,
Different business models. Many, if not most specializing in exterior wood, build long term relationships with their customers. By definition, that means maintenance. By gross sales each season, that means a skewed geometric business growth over time.
Most of us can make ipe' look like God's gift to man, day one. WT, RS, BM, Assie Oil, Penofin, Messmer's, Sikkens, F&P, Behr's, CWF, does not matter. What matters is value to the customer.
Attached are two pics of WT on unweathered, "unseasoned" ipe'. Six months of NJ weathering over the winter. No sun exposure to speak of. Job was ~ $ 2K out of his pocket. Not a stain fault, a wood prep fault.
Think the customer is happy? Think again.
