RW> Just the opposite from my perspective. That dirt will crud up the paint,   
   RW> requiring a cleaner to make it shine again. The Z has been in the garage   
   RW> gathering dust. I use a 'California Duster' to keep most of it off, but   
   RW> the last wax job has accumulated dust to the extent that it now clings to   
   RW> the paint and the duster can't remove it. Time for a good 'hand wash' and   
   RW> wax...Since it has been sitting outside in the Texas sunshine since   
   RW> January, that will make the cleaning job that much harder. Even the   
   RW> touchless car wash couldn't cut it.   
      
   The dirt will crud up the paint and requires some major scrubbing to get   
   through it all.  The first time I used the Nu-Finish, I had to really scrub   
   the trouble spots (the hood) where it looked like some oxidation had taken   
   place. The Nu-Finish was able to bring the shine and gloss look back to it.     
      
   I also like the fact that it lasts a long time.     
      
   RW> 8^) When I bought the Z in 2001, it got a wash job every week. A wax job   
   RW> about once a month. At the time, I used Mother's Wax and a Mother's   
   RW> Showcar spray to keep it shiney...that's all gone now, but I still have   
   RW> the Mother's...   
      
   I use Mother's Chrome polish on the HD.  That stuff does a good job, too.     
      
   RW> If you got any on your black bumper parts, you can tell when that stuff   
   RW> is   
   RW> gone just by looking. If the stain it leaves is gone, the likelyhood of   
   RW> what you applied to the paint will be too. At least Mother's can be   
   RW> washed   
   RW> off if you scrub long and hard enough. Not so with Nu-Finish.   
      
   I just make sure I get all the wax/polish off and don't put it in hard to   
   clean areas.  The downside of not being able to get the Nu-Finish off after   
   long periods of time if not scubbed off is probably one of the reasons that it   
   lasts so long as a wax.  I have never seen a standard wax last almost a solid   
   year.   
      
   RW> There has to be a touchless car wash in your area. Run it through once a   
   RW> week and it'll stay that way, for a while.   
      
   Even the scrubbing car washes wouldn't have cleaned my car, originally.  Too   
   much scum and oxidation on it.  After some scrubbing with the Nu-Finish, it   
   looks new again.     
      
   The winter months are much more harsh on the paint than summer, given all the   
   salt in the winter.  I try to get that cleaned up quickly.
