I live in Hyderabad, India. Bril Royal Blue is available in a few stores, but mostly the date of manufacture is 2009 or 2010. Is it safe to use it in Indian ebonites (ASA, Gem, Deccan) ?. I have used a batch manufactured in 2009 in ASA Athlete, ASA I Can and the Gama Raja, did not have any issues, but I am wondering if they will cause any long term damage (corrosion of feed, clogging channels, harm the ebonite).
Has anyone faced any such issues with Bril's Royal Blue ink?
I ask the store owners if they can pull out some new stock, but in most cases either they don't have it or they give the usual .. "Bril is no more, stock isn't coming through"... which cant be true as I still get latest batches when I visit Bangalore.
