Epson r1900 dont use default cd/dvd settings

Epson prints with r 1800/1900 on cd/dvd media smudge when touched with a wet finger even on TY watersheilds, or am I using the wrong media/settings

Whats the best media and settings to make the discs waterproof ?

i have started not using the cd/dvd settings , instead I put it on cd/dvd tray,photo paper glossytext and image or photo and it sprays gloss over the cd making it water and smudge proof.

It sounds as though you are using pigment-based ink.
Best performance from printable media is achieved with dye-based inks.
Hopefully your coating can encapsulate and stabilize it.
