TOH Top 100: Weathered Wood Accelerator by Varathane
This replicates nature's aging process for you, but in a tiny fraction of the time
This penetrating finish reacts with the tannins in wood to create a rustic barnboard look in 30 to 60 minutes. The higher the tannin levels, and the longer the finish sits, the grayer the results.
