Can anyone give me any hints on tinting poly? The advice I have been given (You may have guessed that we don't get much call here for tinted poly) is that it does take longer to tint than CR39, and that it cannot be kept in the tint too long because the heat may ruin the lens. The same person who gave me this advise, also said that it is impossible to achieve a dark density.
The job this relates to is for a sports shooter who requires a rather heavy yellow tint, with multicoat, and I have been told by Sola that it is impossible. Essilor here in Australia says that they won't even attempt to tint poly at all!
Is there a certain brand of tint that will work better than others for poly?
All feedback will be appreciated. :)
Corey.
