Some of the performance benefits you're seeing from Awlgrip comes down to the final dry film thickness. From the TDS they recommend at least 3 coats at 2-3 mils per coat (dry). So 6-9 mils DFT.

Auto urethanes are generally thinner: about 1mil DFT per coat times three coats is 3 mils. So to compound the material cost difference you're also using two to three times the amount of product.

For comparison, here are some typical varnish applications (over epoxy):
Z Spar Captains: 4 coats at 1.5 mils DFT = 6 mils
Interlux Perfection (2-part urethane varnish): 3 coats at 1.2 mils (DFT) = 3.6 mils

For your usage it's no wonder the Awlgrip 2k works great for you.
