The way I have used it, as a final coat after multiple coats of stain, it dries hard and clear. The only cautions I have are these. I haven't used it on a true hardwood yet, maybe try it where it won't be seen first. If the finish is already damaged anywhere it will turn out uneven in a way that will be very difficult to fix.
