Have you ever ended up paying a
high-wage carpenter to spend time
scraping old masking tape off of a
painted window? It's not exactly an
efficient use of resources. Next time,
try using Cantech's 7-Day Outdoor
Masking Tape, which the manufacturer
claims will pull away from glass without
leaving a residue, even after seven
days of exposure to direct sunlight.
The tape is available in widths from
12mm (about 1/2 inch) to 72mm (27/8
inch) so it will work in applications
from brush work to spraying.
