You can shoot the underside of the tub with raptor liner for less than $200. But if your using some kind of rubber undercoating im not sure the cost.
You can shoot the inside of the tube with tintable raptor liner for about $200. The tint you have to get mixed at a paint jobber is another 2 or 3 hundies.
Just see what there using. And when they say it only takes a hour or so to set the tub and bolt it down......maybe if you dont have doors. After i bolted my tub down i spent a week adjusting body mount shims to get my door decent. Start with at least 2 washers on top of every body mount....that way you can pull just one washer rather than adding 7.
Good luck and have fun. I got one of the last KENTROL bodies made. I freeking love it! Ill take a rip down salt covered roads in minnesota any day! I wish the entire bronco was glass but thats not possible. Plus some pof the glass parts like tailgate and grills just dont look real enuf to me to use. the metal inner front clip is a must, and the detail in a steel grill and gate cant be matched with glass.
