Easy, looks great, easy to install.
I bought the cab corner cover and the smooth starter kit. After painting per the instructions, it took about 1 1/2 hours per side to install. Looks great. I used the included instructions and watched the you tube videos on the website. The one item I would recommend is that after you cut away the rust and file down the sharp edges, test fit the quick cover several times to make sure you can put it exactly where it needs to go. When you spray the rust inhibitor and apply the heavy grease, you do not want to drag the quick cover on the greased surface. They give you plenty of adhesive tape so if you screw up placing it on the cover or when you are installing it, pull it off and redo it.
