Will Paint Thinner Damage Paint On A Vehicle?

Paint thinner is not necessarily an aggressive substance and can sometimes be confused with paint stripper. Paint stripper should never be used on a car but if used sparingly, paint thinner should be fine to use on your car. If you are purchasing it from new, it would be best to find a subtle variety of paint thinner and you can ask the staff at the shop you are purchasing it from for some help, as they are usually knowledgeable in hardware stores and more than happy to help.
It is a good idea to first of all test it on a discreet area of body work where it does not matter if it does fade the paint. This is unlikely to happen but it is best to do a tester to begin with. A tester can be done somewhere such as the inside of the door. Begin by applying a small amount to an old rag and gently dabbing it against the paint. Wait a few hours to establish whether there has been any negative effect to the paintwork and if not you can carry on with the rest of the vehicle.
Paint thinner is often used to remove oil based paints or to remove contaminants or scrub marks. Paint thinner is extremely flammable so ensure you keep it away from the engine of the vehicle and be careful not to spill any. You should also be careful not to get any of the paint thinner on yourself. Follow the directions on the packaging as incorrect usage can irritate the eyes and skin, damage the nervous and respiratory systems, and cause kidney failure. Protective clothing, including gloves and eyewear, should be worn when handling this type of paint thinner.

The paint on your car is baked on. The paint thinner will not remove the paint but it will remove road tar.

My old boss who used to be a auto painter had me use it on his truck to get other paint off it worked great I can only  guess that your clear coat protects damage.I checked this out just to make sure and figured I would add my own exp. I'm going to use on my truck tommorow but only on the bottom where the road sludge is

I used it to remove road marking line paint and it worked fine. It did not damage the vehicle paint.

Paint thinner should not do anything to your paint we use it all the time at my shop to remove pin striping.

I used paint thinner to remove tree sap that dripped onto my car while parked under a pine tree. It worked great and no damage to the cars paint.
