i just pulled the front axle off of my sub and was wondering what i should put on it after i get done sandblasting it today. is there any rust protection product that stands out from the usual undercoating. also im bout to install the bodylift in like a week and i was going to sandblast the frame and use the same stuff. but for the underbody. has anyone ever used herculiner or what. just thinkin bout it. anything you can think of would be great.
