I really want to try the Alumi-uv, but can someone give me an idea about the coverage? I'm curious about how long a $30 4oz bottle would last? Approximately how many average size crankbaits (1.5/2.5) it would cover with a single coat? Some way to compare the cost verus 2-part epoxies. The stuff is expensive, and It seems like it would at minimum triple the cost per lure.
