Paintless dent repair, PDR ? PDR is a specialized form of autobody repair where technicians use special tools and techniques to slowly reduce a dent down in size until it completely disappears. PDR is a learned skill. Through trial and error, technicians gradually begin to understand the specific areas of a dent to manipulate, exactly how to manipulate certain locations of a dent, and the specialized processes and technologies used to remove a dent without the need to repaint the area.
First, you have to pick a proper tool kit. And that’s not easy for a user who has little clue what’s going on. Some of them are cheap — low prices should raise red flags. Others are so expensive (three-figures or more) that they’re probably right up there with the cost of a decent professional repair (although, to be fair, if you buy the kit you can perform multiple repairs). Many of the high-end, expensive tools are intended to be used along the inside of the panel, much like a pro would do. (Gaining access to the inside of body panels can be a chore, though, and often involves careful removal of multiple interior trim pieces.) Alternatives (which tend to be the less expensive kits) flaunt the conventional wisdom that small dents should be massaged back out from behind the painted surface. These options instruct the user to glue a tool to the dented surface and then twist or pull on the tool to pop it out. True, you can go buy the same tools as a pro, but it takes a lot of skill and experience to use them properly.
Apply the dry ice as many times as you need to, but it should pop out eventually if the dent isn’t too deep. You can also try heating up the dent first, with something like a hair dryer (similar to the hairdryer and compressed air tip above), and then apply the dry ice to it. Suction is one way to get out a dent, but the problem is finding a dent puller with the right amount of power. Well, why not just create your own? All you need is a pot (or bucket), a vacuum cleaner and some tape and you can get that dent out of your car in no time.
Repair times are up to the severity of the hailstorm and the damage on your car. For the light or moderate damages, the repairs may take from 1 to 3 days. But for heavy damages, it may take you 2 to 3 weeks as that damages will needs body shop participation, for paint work and panel replacement.
For dents that are fairly small and not deep, a dent repair kit may be an inexpensive and simple solution. These kits are available at any auto parts store and tend to be very user friendly — instructions are always included. The best part is that they usually cost under $40. Most include several stems for various sized dents, a glue gun and a knockdown tool. You may be surprised at how well the kit works and how professional the result looks. We don’t recommend this kit for large, deep dents — you might cause even more damage trying to fix those with a kit. Read more info at Restoring your hail damaged vehicle.
