Apply a small amount of super glue on the outer rim of the wheel. With a toothpick spread the glue evenly around the rim.
With the polished side of the wheel cover facing outwards, drop the wheel cover into place.
Apply pressure with the eraser of a pencil. Then run a clean toothpick around the outer rim of the wheel cover to securely glue it in place.
Handle the wheel covers with care to prevent creasing.
Prepare the wheels, including lubrication, before installing the wheel covers.
"Gel-type" super glue works best.
