Chances are if you live in a fairly large city, you will have some kind of mobile service to remove dents. Paintless dent removal is the most common, however, in recent years mobile automotive paint services have been working hard to create at-home solutions.
There is a reason that all automotive body shops have paint booths. They are totally free of dust, small particulates in the air, and many other features to protect society at large from the harmful metals in the paint. Most of these mobile paint solutions are running their operations outside the law. If you look beyond the surface you will find they do not have businesses set up with your current state. Also, many of them do not have yelp or google Business accounts because they know the inevitable negative reviews.
Most of these operations are shut down before they become too large, but the damage is often done, too late. Poor repairs are almost comical: when you pass the vehicles worked on the road, they stand out like a sore thumb.
With Paintless Dent Repair, you keep your original paint. Everything is original. No need to poison your neighbors with toxic chemicals outlawed in neighborhoods. If they claim to not use those chemicals then you can be certain, it will be a very poor job, since the very best paints, must be used in a body shop setting.
