I haven't a done a windshield for my road glide, but a friend of mine did a small windshield on a headlight cowl. It was clear and he wanted it completely black so I helped him darken it. We used the VHT nightshades and one can of clear coat. It's important to wet sand the shield with a maximum 800 grit sand paper and no coarser. Once it's nice and sanded smooth (should just have a nice smooth frosted look with no heavy sratch marks, if it does then you need to sand down with a finer grit paper until it's gone). After spray a light coat of the VHT, wait about 5 minutes, then spray a second coat. I might add the can sprays quite nicely and evenly. So usually 2 coats is good if you don't want it completely black. A 3rd coat will most likely black it out and that's what we did. Once you complete the VHT nightshade, wait about 20 minutes and then hit the shield with the clear coat. We did about 3 coats of clear with 15 minutes between coat. Once that cured over the coarse of 3 days I wet sanded down all the orange peel with a 800 grit, then 1500 grit and lastley 2000 grit and then compounded it with med/fine compound, plastix clear wax and then a coat of mequiars wax and it turned out real good.
