I you haven't done any wash before. Then its easier for you to learn.

I'm all acrylic after priming( I don't have access to Badger Stynylrez primer ).
The best thing about acylic wash is you save a lot of cotton buds or Q tips. And theres no lint left over by the cotton if you use a solvent based wash.
Surely, other modellers will argue solvent based wash is better due to there capillary action when applying it.
Like I said, you need a different mindset when using acrylic wash.
You can still use the Future for surface preparation for wash. As long as you let it dry for a day.
On my side I use Vallejo Premium Color Polyethane Varnishes since I cannot get future in my country. In my book. "Best set of Acrylic Polyurethane clear Satin Matt and Gloss varnishes" I ever used.
