In my opinion, the MudBuster fender flares for the P1000 is lacking a little bit. They do offer much better protection but they could be almost perfect with a little modification. They also have clear instructions with pictures and provide plenty of hardware. I'll explain with some pictures.
In this picture you can see the front flares taper in toward the front. It looks good and I'm sure it keeps them from getting broken.
Here is a picture of the water spray that I believe could be prevented if the front fender coverage extends a little more.
Also, the rear fender flares had to be cut to fit. The following pictures shows the problem area.
You can see the rough edge where I cut to clear the frame gusset/bracket.
