I haven't. I'd guess you may not notice a difference in final cured form compared to pure tung oil, but the cure time should be shorter. Use chemical-resistant gloves to apply it (may cause skin reactions), and work in an area of good ventilation, along with whatever other safe usage protocols. The product listing links the MSDS for the product, and about 25-30% of the product is solvents and/or curing additives.
