or prolonged skin contact or inhalation of vapors can be toxic. Use a well-ventilated area, wear
gloves, and keep away from sparks or flame.

and a stiff brush.

adhesive is tacky but will not stick to fingers.
(e) Starting with an end, carefully attach the gasket to the metal. Press into firm contact all over.
(f) Minor dents and bent edges can be straightened using common sheet metal repair procedures.
