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 considerationswe 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.
