Apply to the front fender, mold it to shape, do the same for the other side, then move to the rear. By the time I am done with the rear the fronts have hardened a bit, but the smooth type is still maliable for an hour or two, so I can reshape them as needed to get them as even as possible, repeat for the rear, then I let them dry overnight. The next day I use sandpaper rolled into a tube to shape the insides. Use a heavy grit so that it will last all four fenders, then more to a lighter grit for touch up, do the top with a finer grit. I use a sanding block for the edges trying to keep a continuous flow from from to back. It's tedious, but it gets the job done pretty well. They are a little off, but you don't notice it without looking hard.

ok thanks surgeon!
