Well.. I think my 'patina' went too far..
* gave the dial a light coat of Mr Hobby 'Mr Super Clear Matt' (lacquer) and let it dry for a few hours.
* Took a role of blue painters tape and made a tinfoil pocket inside.
* 405nm LED UV Light (~6w used for curing 3D prints)
~11 hour later (7pm to 6am).. I had this:
I wanted just a small amount of discoloration... not a pink dial
Do I keep going.. see if it ends up full tropical? Or leave it as is? I bought this dial to mess around with... what should my next move be?
