SIG canopies are not made of butyrate plastic. They are made of PETG plastic.

We haven't used butyrate plastic for at least 10 years, maybe more. If you successfully dyed a SIG canopy in the meantime, you had one that was old stock.
Bottom line is PETG will not accept dye of any sort that we have tried.

Well, the canopy on my Somethin Extra (purchased 12/05) tinted up very nicely. I seriously doubt that kit was 10 years old.
Just tinted mine on my Somethiin Extra a few days ago. While it did take longer than the Skybolt up there a few posts, it did take the dye. No salt, no vinegar.
