Omega dry is no different than many other dying agents.
It contains ethanol (reduces surface tension), amine salt (confers gloss and smoothness) and surfactant (proprietary).
So, Omega would improve sheeting (hydrophilic) and possibly bead-up (hydrophobic) of rinse water. You can’t say for sure though because surfactant is not identified.
Samurai contains “same ingredients” as omega dry except samurai contains siliconized wax (not established).
If its copolyol wax, it would improve sheeting effect. If it’s a combination of carnauba and copolyol wax, it would improve sheeting and bead-up.
So, omega will not work as well as samurai. It doesn’t contain any wax.
