I've been a woodfinishing professional for over forty years and I've been using this product since it first came out and recommend it for all wood finishing projects. The best way to apply it is by the spray method to allow a more evenly flow.. it will never turn “yellow or amber” because its a waterborne product and doesn't have the same resins that the He “oil Based” products have that cause that “yellowing/amber” tone over time. Because its a coalescing film it does not dry the same way as a reactive or evaporative coating and will not “flow' out as smooth as those coatings why it's applied by the brush or roller technique therefore, I recommend spraying or adding an extender or floetrol to allow for a smoother finish for brush and roller.
