Superglow is Gateway’s glow plastic, with a heavy strontium-based luminous fill. Six moulds are listed in it, mostly putters.
Glow plastics stiffen a little and give up some grip against their base, and Superglow is on the mid tier for durability rather than the premium one.
Don’t dye it. And it isn’t as tacky as the SureGrip putters, which is the price of the glow.
