How many PTG do you need for a car?
2?
one for the metal parts and one for the plastics bumper or some fiberglass body like the corvettes?
Also, somebody recommand the highline meter but i think this PTG is only good for the metal.
Finally,if i need one, is their a PTG for the plastics that is under 500$.
Thanks for the help

The $279 highline PTG will do metal (ferous and non-ferous) so most likely steel or aluminum panels.
The Defelsko 2000 is very expensive since for composite it uses ultrasound tranduscer instead(no hall effect here like PTG for metal). It emits 1Mhz-7Mhz signal to penetrate the car and look for change in density(assuming body-panel, primer, paint-base and clear coat has different densities). yes this is like medical ultrasound machine looking for tissue density vs bone, fat etc.
At the end it depends on what your applications? For hobby or profesional detailing?
