[India Source] Resins based enamel colors

Hi All,

We have an Italian enamel setup (resins based), my issue is these
guys are very lazy.

Whenever I call for enamel colour, they take lot of time to ship us
the supplies (some time a month) and this is prohibitive plus the
cost of freight again killing me.

Can someone suggest me any enamel colours that is available in India?
so that we can get the supplies sooner without hassles of importing
from Italy?

Any other suggestion welcome.

Thanks in advance
