I used my car a a carp fishing wagon and its been through a few hedges in its life!! Its covered in RDS so its taken a serious amount of time to get these out of the top coat, im sad to say some of them are too deep to remove but i have achieved a 90% perfect finish i belive. Being a DA too it takes twice as long as a rotary for a correction as its safer. Im no expert im still learning but 50 hours being carful is better than a strike through.
You can only really do a correction like this maybe twice on a car in its life depending on how much paint/clear has to be removed, if i was to do a car twice i would take paint depth readings all over the car to see what im working with
