Just got back from Alaska. The mh was totally covered in muck from driving through road construction sites. I power washed it twice while on the road but only removed the surface grime. Since I have been home, I have washed it twice with hot soapy water and it looks clean but when I rub my hand over it, it feels like sandpaper. The mh is only a little over a year old and it has that paint protection thing and it seems that the sand has embedded itself into it. Anyone else with this problem?
