What is the best way to prevent tropical hardwood deck lumber like ironwood from developing a gray patina in sunlight?

From Trevor Neale of Blastco on April 9, 2020:
UV radiation delignifies the surface even with a clear coating containing UV absorbers. As already mentioned, let it age naturally and enjoy its unique patina!

Leave it alone.

I wish you could explain it to my customers. They all want it to look like the day it was milled, forever.

From Dave Helmholdt of Repcolite Paints on April 6, 2020:
The best answer is you don't. The best part of using a wood like ironwood is you don't have to stain the deck as part of its upkeep. You just get to enjoy the deck. If you want to stain a deck a certain color, pressure-treated or cedar lumber would make more sense. If you truly want to try and maintain some color of the ironwood, then using a very slow oil that can penetrate into the ironwood would be best. Just know that depending on sun exposure, you may need to do this very frequently.
