For 1990-2009 cars

Caution: When using power tools that may create smoke when cutting urethane sealant, work should be done in a well ventilated area and/or with a NIOSH/MSHA Approved air supplied respirator to prevent possible harmful exposure.

When the urethane adhesive is heated enough to give off smoke, high levels of methylene diisocyanate (MDI) may be present. Unprotected exposure to methylene diisocyanate (MDI) may result in severe, chronic, debilitating respiratory problems.
