Another quick update, after trying unsucessfully with several different Chineses factories, we have decided to return the lenses back to Australia and get them done at the same place where the clear engine covers are manufactured (Sydney Company), so that we can have complete control over the process and get the desired result for you all.
We would like to thank you all for your patience in regard to this project, as we could not forsee the time blow-out, ridiculous quoting and time turn-around from overseas companies.
