When I was restoring my 1986 Pontiac Fiero, I found that the factory stickers were no longer reproduced. I was able to make stickers for myself, as well as start to manufacture stickers for other Fiero Enthusiasts. The Polyester material is a very close match, if not an exact match to the original stickers that were placed on the car when it was new from the factory.
I use a Silhouette dye cutting machine to precisely cut out the stickers after printing them.
