Iit can be possibly applied but because of the length of time it takes t dry it is best u take it off the car. For safety sake u should let it dry for about 36 hours. Also there in another post here where someone did their rear say bar bushin, he put up some pics of it.
I just did my 4 mounts, I got the 3M windshield urethane medium softness at dollar savers on the bamboo i'll post and report how much vibration and how durable it is.
