Hey Kyle, I tried the DupliColor Spray-on Bedliner in a spray can on some of my suspension parts like the sway bars, the spare tire rack, and the inside of the tailgate. It takes 2 to 3 coats to get any thickness, and it has rubbed off in a few spots. The stuff looks good when just applied, but it is just not as good as Linex or Herculiner. If you have no rust on your frame now, see if you can find out if it was ever "undercoated" either from the factory or at the dealership when new. If so, the undercoating will last about 20 years before it begins to flake off. Your bronco is new enough that it can still be done for a reasonable cost ( couple hundred bucks) and last you for years to come. Any Ford dealership can do it. In my case, I used a product called "Restore" from NAPA that I just brushed over the frame and axles and it looks great!!! Cheaper than P.O.R., too. My Bronco was undercoated when new, but most of it has since peeled off. It is 20 years old, after all!!!
