Arm R Seal is a better product IMHO. I experience it to be more durable. It applies about as easily as Minwax's wipe on poly.

Your other option is to purchase full strength Minwax polyurethane and thin it 25-50% with mineral spirits.

Two more options for your consideration:

Waterlox Original Sealer Finish (Original formulation). Phenolic resin wipe on varnish. Darker than AS or MWOP. I find it is excellent for this reason on walnut and cherry.
Rubio Monocoat or Osmo Polyx. These have gained popularity in the past couple years. They are "hard wax oils" (not fully sure what this means). But they have very low odor, and they only need 1 or two coats. They are not as durable as the varnishes above, but for a turning it may not be an issue. I love these for their ease of application. Not appropriate for a gloss build.
