If windshield repair the source of the noise is the heat shield all you have to do now is to tighten it up. Turn off the engine first then go underneath the car. With your good old screwdriver, tighten all the bolts connected to the heat shield and I mean, every single bolt. While you are already down there, check if the heat shield has been twisted or curved. You can fix a bent heat shield through a pair of pliers or a screwdriver. Pull the heat shield away from the spot where it makes contact with the exhaust pipe.
If the crack looks exactly the same when completed, it's very likely the technician didn't inject the resin properly. A properly completed repair with cause each area of the damage to disappear from at least from one angle of vision (ex: looking from one side, looking from below, looking from above, etc.).
If the chip is smaller than a quarter and the crack is less than 12 inches long, they would most likely provide service to you at the convenience of your home. The repair kit they will be bringing will contain several materials, tools and equipment. This would include a windshield repair bridge that is self-leveling and is able to reach anywhere on the windshield together with the injector. A crack expander that slides easily and reaches low on the windshield. An A.C. powered ultraviolet curing lamp and a 15 watt, 22 inches bulb for curing long cracks. A drill if the chip needs to be cleaned. A curing film that enhances the ultraviolet rays for faster and complete curing, a UV protected syringes designed to protect the resin from the sun's ultra violet rays, the resin and some other stuff.
On most car windows there is a small triangle printed from the manufacturer. Under the fix auto glass repair serial number is a small point with a number. This is the year of manufacture of the window. With popular car models this figure represents the model year. For example a 7 would indicate a model from 1997. If one window has an alternative number it may mean that the window has been replaced due chip or crack damage (windshield) or burglary (side window). If the windshield and side window have a different number from the rest of the windows, this could mean that the car has had a collision. Due to damage the windows have been replaced.
The next morning, we woke to a heavy, hot task of cleaning up the mess of limbs and leaves. We surveyed the damage. Fortunately, the heavy tree missed our carport by a foot. And only a few boards on the wooden fence needed to be replaced. It would be a fairly simple repair job. Next we moved onto the task of clearing away the fallen branches. Rick used his chainsaw to cut limbs into manageable sizes. I raked limbs and leaves into a wheelbarrow. Everything was neatly arranged in a pile in the front of our home for pick up.
Just a month earlier, we were talking about this tree. That it was time to come down. The grass wouldn't grow, it affected our other tree's growth on one side, and it wasn't a long living tree. Rick actually had begun the quote request on tree removal from a few vendors. And while I was relaxing in the wind that night, I was still debating on whether or not I was ready for the tree to go. I really liked that tree. It blocked my back door neighbor's view into our yard. It brought robins, cardinals, blue jays, and mourning doves to the yard. It displayed fiery red leaves in the fall and bright white buds in the spring. Well, Mother Nature settled my debate for me!
America is the land of opportunity but that doesn't guarantee success. Trying to start a windshield repair business on your own without any marketing guidance or help is a recipe for failure. Sure, you'll get a thin marketing manual with the repair kit you order from XYZ windshield repair company. But, more than likely it's outdated and not going to be much help. Believe me I know. I wasted more money on marketing my business using the marketing ideas I was given when I purchased my repair kit than I care to remember.
