Re: bmw-digest V9 #1530

Regarding keeping your dash from cracking.  Do not use a preservative that 
contains formaldehyde (sp).  Do not use armor all.  Use one that is not 
silicon based but that has a good UV blocker.  Note that the damages is 
mostly caused by UV rays and high temps.  Window glass will block UVA rays 
but UVB rays are the real problem as far as UV.  The high temps and UVB  
destroy the plasticizers in the dash.  Modern dashes are pretty good about 
not cracking.  One good product is Griot's Garage rubber and vinyl dressing.  
 There are other good ones also.
