I know there have been topics discussing tar removal before, but someone told me that pain thinner would be good to remove a lot of tar from you car. Has anyone tried this before? This tar is caked on, has been on for at least 3 months, and there is sooooooooo much of it! We're not talking a spot here or there, we are talking almost a sheet of tar running the full length of the car all the way up to the middle of the doors! Holy crap! I may try using orange clean, but wanted your opinions on the paint thinner idea first. Thanks!!!
