in my experience with that bondo crap..nothing was able to completely cover it.. i tried 4 different products (trim shine, mcguires, black again, turtle wax ice) i think mcguires did the best job hiding it, its not noticable at all anymore (close to a year later) right after a good coat of mcguires... after 2-3 weeks when the mcguires starts to wear off, it becomes visible again... that stuff is brutal
