My friend has a truck he bought not to long ago and has been slowly fixing it up and it is looking great . When he removed the tail gate rail to replace it with a new one he discovered that the og owner had put liquid nail on to hold the old rail on . After putting the new one on he discovered that a some of the liquid nail shows just below rail on the outside of the bed , so my question is . Does anyone have any ideas how to get this off without hurting the paint and having to repaint ?
