For finishing the process, remove the syringe. Afterwards, the pedestal and disc have to be removed using a razor. If there is any front window repair compound still present, then use the razor for cleaning it but do it very carefully so that the glass with not get scratched.
Driving the car immediately after a windshield replacement is not something you can do. There is a time period that should be allowed to make sure that the window has settled and dried. The warmer weather allows for the adhesives to dry quickly. However, the colder weather increases the time that is needed before you resume driving. Taking the time to wait for the adhesives to be at full strength could mean the difference between life and death or an accident that leaves you maimed.
Determining the ARV is a fairly simple process and definitely the most important. This is where you should spend most of your thinking time and efforts. One of the easiest ways to do this is to get a CMA or comparative market analysis or "comps" from your realtor. When a realtor gives you comps they show you notice I didn't say tell you what price other houses that are similar to the one you are looking at have windshield repair sold for in the past months.
However, before asking for an entire replacement that could cost hundreds, consider a few different types of solutions to fix the windshield. Look into a windshield chip repair kit. You can get one with enough materials for multiple chips or you can also buy a disposable kit with a syringe that is tossed after one time.
Another way to figure out ARV is to get an appraisal from a certified appraiser. Yes this costs money, but if everything else looks good about the deal and you are uncomfortable with the realtor's comps, you can always get the opinion of another professional. They go more in-depth when appraising properties then realtors might. However I only trust the appraisal when I actually hired the appraiser. This way I know that I have given him/her the instructions on how I want the appraisal to be completed.
There is no reason to drive around with a broke up windshield. Auto glass replacement is simple and easy. Finding the company to do it for you might take a little finger work but it's worth it. You want your car to be safe while you are driving on the road, and a broken windshield is just not really that safe. Take the time to find that company for you.
