I dewhisker very time I wet sand to fill the pores.

I had a stock finish whisker once about 30 years ago. That happens when you apply a non-penetrating finish to bare wood, like polyurethane, lacquer or even TruOil if it isn't thinned. Once I started thoroughly soaking with thinned finish for the first few coats and wet sanding to fill the pores I never had to include a separate dewhiskering phase.
