AS A BUMPER FINISH RESTORATION TREATMENT.
I've known of this for years but never tried it until today.
There was a little bit at bottom of the jar ,although a bit on the dry side I decided to give it a try.
The front bumper was quite a mess .
I applied a little with a cloth, rubbed in the p. butter.
The oils in it put a shine to Black surfaces.
Made a big improvement to its
20 year old appearance.
Doesn't wash off for some time.
I used it on front bumper ,
both mirrors and door handles.
Note the dull untreated side panels.
