•	AGRSS guidelines for installing a used bonded windshield, door, vent, quarter, or rear window back glass The term “used glass” can be defined as a part that has been previously installed.  Each piece of used glass must be evaluated on a case by case basis.  The AGRSS Standard requires that the part be free of flaws, compatible with the new adhesive system and have a traceable path to the previous installation information.  The adhesive manufacturer has specific bonding requirements to insure a safe, quality installation.  The used part can ONLY be used when all questions about it are answered, and the part meets BOTH adhesive manufacturer AND AGRSS Standard requirements. The chart below is the AGRSS standard that all auto glass companies and their technicians are required to follow.  The AGRSS Standard (AGRSS/ANSI 002-2002 Automotive Glass Replacement Safety Standard) is the first and only North American standard detailing the steps and procedures installers should take to provide safer automotive glass replacement.  It is one of the most significant safety developments in the automotive glass industry in the past 50 years.  The AGRSS Standard explains what steps should be followed for safer replacements and also sets up procedures for handling difficult or problem installations.  It was developed by a dedicated group of automotive glass industry professionals under the auspices of AGRSS (Auto Glass Replacement Safety Standards Council).  The entire development process followed the procedure of the American National Standards Institute (ANSI) to insure that it was open and complete.  As a result, the auto-glass industry has a standard that received input from and belongs to the entire industry, not just one group or company.  It is important that every single person and company involved in the auto-glass replacement industry be familiar with the AGRSS Standard. INSTALL GLASS According to Dow Automotive Procedures and the AGRSS Standard STOP DO NOT INSTALL Does not meet ARGSS Standard STOP DO NOT INSTALL Does not meet DOW Automotive Requirments Did Your company install the glass in the vehicle it was removed from? No Yes Was the glass original equipment in the vehicle it was removed from? No Yes Was it installed according to the AGRSS Standards? No Yes Does the urethane bonding surface on the glass meet all of the following 3 conditions? •	Freshly Cut •	Well Bonded •	Uncontaminated No Yes Does the body-side bonding surface meet the same conditions No Yes Guidelines for Determining if a used windshield, door, quarter or back glass part can be installed ? Are you sure the method of removal has not contaminated the bonding surface Yes No AGRSS
Surface   contamination   is   and   always   has   been   an   on   going   problem   in   the   auto   glass   industry.      In   2003,   after   a   lot   of   extensive research,   Dow   Automotive   implemented   a   working   solution   for   the   problem   on   “new”   glass.      Dow's   mission   was   to   define   the   types of   contamination   and   provide   a   practical   solution   that   is   effective   on   a   wide   range   of   contaminants   and   safe   for   the   auto   glass technician   doing   the   actual   work.      Dow   concluded   that   the   contamination   could   be   classified   into   one   of   two   types,   "primary"   or "secondary"   and   that   both   could   be   effectively   treated   by   the   technician   using   materials   typically   on   hand   in   any   properly   equipped auto   glass   installation   center.      Most   contamination   can   be   classified   as   "primary"   contamination   that   is   the   direct   result   of   the manufacturing   process   or   shipping   from   the   manufacturer   to   the   distributor's   warehouse.      Dow   developed   a   "wet   scrub"   procedure for   "new"   auto   glass   parts   a   technician   can   use   that   can   virtually   clean   and   make   just   about   any   "new"   auto   glass   part   usable.     Secondary   contamination,   is   typically   the   result   of   handling   or   transporting   the   glass   part   and   is   usually   easily   treated   with   a   good "commercial" cleaner. In   2004   Dow   Automotive   released   the   "wet   scrubbing"   procedure   to   the   technicians   in   the   auto   glass   industry.      This   procedure uses   a   mist   of   cleaner   that   is   applied   to   the   bonding   area   of   the   glass   that   will   produce   an   indication   of   existing   contamination.     This   particular   cleaner   will   usually   indicate   a   contaminant   is   present   on   the   glass   by   “separating   or   fish   eyeing".      If   this   happens the   glass   bonding   area   is   cleaned   and   tested   again   by   reapplying   the   cleaner   to   determine   if   the   contaminant   was   removed.      If   the cleaner   does   not   separate   when   reapplied,   the   contaminant   was   likely   a   "secondary"   contaminant   and   was   successfully   removed and   the   glass   in   now   ready   for   the   application   of   the   adhesive   system.      If   the   application   of   cleaner   continues   to   "separate   or   fish- eye"   a   primary   contaminant   is   likely   present   and   more   cleaner   should   be   applied   to   the   bonding   area   and   it   should   be   lightly scrubbed with a non woven abrasive pad.  After that process, the glass part should once again be re-cleaned and reinspected. If an auto glass technician "wet scrubs" a piece of glass more than three or four times and it does not appear that the contaminant is removed, Dow recommends that a new piece of glass from a different manufacturer should be used. By the later half of 2008 Dow Automotive has had nearly five years of proven results with this "wet scrub" process and it  is still being supported by continued testing and well over a million installations.
It   is   highly   possible   that   the   bonding   surface   maybe   unstable   or   contaminated.      Contamination   can   come   from   many   sources   and   can consist   of   one   or   more   substances.      It   is   difficult   if   not   impossible   for   an   auto   glass   technician   to   accurately   identify   the   contaminant   and know   of   any   special   treatment   procedure   for   removing   it.   This   was   and   remains   a   problem   even   on   "new   auto   glass".      A   used   glass   that has   been   out   in   the   world   for   a   number   of   years,   and   removed   by   who   knows   what   method   from   a   vehicle,   has   even   more   hurdles   to over come
Due to job cost considerations we do not offer this service for mobile on-site installation, we provide this service only IN House.
I already have the auto glass, will Phoenix Glass install it for me? Yes, but due to economics Phoenix Glass cannot assume responsibility for breakage of your new or used glass.  Also note that if we not not provide the glass to you directly from an auto glass manufacturer or one of our authorized OEM or OEE After market auto glas distributors we cannot warranty the glass itself.
