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.

NOTE: Care must be taken not to damage the roof when using power glass removal tool.

Using a power glass removal tool, cut the urethane seal along the roof from inside the vehicle and bottom from outside the vehicle. Open the hood to gain access to the bottom.
