Gary, ETEX is much thinner and runnier than Devcon Two Ton epoxy and requires rotation for at least twice as long to avoid sags and drips. Do yourself a favor and build a rotator before you try it.
As far as gloss and toughness goes, I think moisture cured urethane like KBS or Dick Nite S81 Fishermun's Lurecoat are actually a bit more glossy than epoxy and tougher for the same coating thickness. They form a very thin, very tough topcoat that is similar to a factory finish. You can simply dip lures and hang them up to dry/cure hard (no rotation should be used). KBS is slower to go off and begin hardening in your storage container, so gets the nod for convenience, but Dick Nite is also fine if you use the "tap the can" method of storing and dispensing it and quickly brush on a flood coat of it before hanging it up to drip off the excess and dry. I use both epoxy and MCU. MCU on plastic baits and epoxy on wood.
All of these are good choices, just depending on the end product you want to achieve and the technique you want to use.
