Applying dry ice to the dent is an effective way for fixing hail damage. The huge change in temperature can force the dents to pop out. Everything for you to do is just moving the dry ice around the damaged area to cool the area rapidly. But be careful as dry ice will damage your skin if you don’t wear gloves when handling it. Fixing hail damage by dry ice can be a cool solution, but sometimes it can not remove all of the dents. So in this case, you will need to do additional repairs.
Restoring your hail damaged vehicle ? Dents near edges – If a dent of any size is situated near the very edge of a body panel or near a seam, PDR repair may be impossible. The reason for this is that in order to repair a dent using these techniques, you need to access the back side of the dent. The dent has a crease – If there is a sharp crease (like a folded page) in the dent, PDR likely will not work. Older vehicles – If your vehicle is older than 1990 or is a classic car, the odds are good that attempting paintless repair techniques on a dent will damage the paint. This is because the paint quality on older body panels can’t withstand the strain of the repair techniques.
First let’s begin with some car paint care recommendations: Clean the Car. One of the most important things you can do to maintain the exteriors of your car is to wash and shampoo the vehicle regularly. Commercial power washes are also beneficial if you use them every few months. Make sure you keep a good distance between the surface of the car and the pressure jet, so you don’t damage the paint. If you’re unsure you could get it done professionally.
So, we’ve explained what the procedure looks like — assuming it was done properly. And as you could probably guess there are a lot of ways an amateur or first-timer can get it wrong. It’s different than most other car repairs because it’s not about mechanical prowess; it’s more about control and the ability to maintain a steady hand and a gentle pace. You can’t rush it. The problem is, once a sheet metal repair starts to go awry, you’re usually much, much worse off than if you’d just left it alone. Metal holds its shape, but only to a certain point. Let’s say you get a dent in the hood — nothing too drastic, just a shallow, even dent with no sharp creases in an area that’s pretty easy to reach. You think it’ll be easy to pop it out on your own, so you begin to massage the underside while holding your shaping tool in place. You’ve made good progress so far, and a casual observer wouldn’t even notice the flawed area. But it’s not exactly perfect, and since it’s been fairly easy to this point, you decide to keep massaging the area to make it flawless. After a few more minutes of massaging, you realize that you’ve pushed it just a little too far. And now you’ve got this flabby area on the hood where you stretched out the metal. And there’s no easy way to shrink it back down. Keep going and it’ll stretch even more. Lesson learned. See more info on Automotive hail repair.
