Any air or moisture left within the damage will show up. It is important to remove all this air and moisture before resin is introduced to the damage. The reason for this is that in many breaks there are hundreds of separations containing air. Air will rise and trap in many of these pockets using average equipment. If the damage has moisture within it and they ALL do the resin cannot bond against the glass. It will set with a slick of moisture between the resin and the glass. Water is incompressible so unless it is removed it will be a problem.
Getting to what a good repair should look like, the dull spot where the pit is should be the only tell tail indication of where the damage was except for the outline of where the damage extended to. This area should be absolutely clear, all legs in the damage should be completely filled and if properly done, should not be seen on the interior of the auto.
Many in the industry seem to think leaving some blemishes are ok, or a few legs not filled are ok. Not true. People who you do work for will see any air left within the damage so it all has to be removed. A good repair is almost totally undetectible.
People doing bad repairs are running rampant throughout the U.S.. We see bad repairs all the time, and these people are actually hurting the reputation of the repair industry even if they don't want to admit it. It is time for many people to get better equipment. Find the repair unit that is designed for vertical damage. If the unit performs well on vertical damage it will work on any other kind of damage.
There is new equipment on the market that try to duplicate the process our equipment does, but these new tools cannot repair vertical damage, and the vacuum is only about half of what our equipment produces. Closed systems cannot evacuate the damage, they merely elongate the air pocket and will not allow moisture to escape the damage. Moisture is the number one reason repairs come out looking poorly. It is a fact that glass actually attracts moisture. This can be demonstrated by simply bringing the temperature of the glass down to the dew point and seeing the moisture form. It was always there, just not noticed.
People that know and study physics agree that to perform the best repairs to glass damage moisture and air need to be displaced first. When operating in this manner (degassing the damage) first, the repairs are far stronger and look far better. If you do not want to change your way of thinking that is your own choice. My opinion is that if you are going to do a job right, you need the right equipment and a desire to excell in your repairs to give the customer what he or she is paying for.
