Door and Door Hinge Seal Replacement

seal away from the door frame. Then use a suit-
able cleaner to remove the remaining seal and
glue material.

free of dirt and oil. Spread or spray a glue which
is quick drying and waterproof onto the area
where the seal is to installed.
3. Install the seal so that the corners of the seal fit
up into the corners of the door frame (3, Figure
2-16).

the same procedure as above for this seal (2,
