• 8992 – 2.0 mil polyester backing and 1.2 mil silicone adhesive
• High dimensional and tensile strength ( 8992 – 37 lbs./in.) for tearing through cured paint
without slivering or breaking
• Resists shrinking, curling, and edge lifting but removes without adhesive residue
• Transparent blue (8991) and transparent dark green (8992) for identification and alignment
