Quite possibly . There is more than enough misinformation out there as well to make a big fking mess of it as well..
None of the places I mention will do damage to a car . These guys do business with me on a wholesale level and I know who the installers are AND their capabilities. if I was unsure of that I would not mention them
That is another kettle of fish. Given there are some of those guys with less than a year under their belt ( vs 23 for me) you would be wise to steer clear there.
