Paint on Cars
I have Used Carb-n-Choke Cleaner, Spray it on, Wipe it Off within 5 Seconds, Or Apply to a Rag then Wipe Affected Area, Used it to get White Paint off the Wifes Mustang, Worked Great, Had to Re-Wax also, As for the inside of the Wheel Wells, Try a Mag Rim Spray, Then Spray Off with a Pressure Washer, Thats how I got it out of there. Did not seem to Harm the Undercoating.
Carb-n-Choke Cleaner works Great on a Rag to get of Tar and Grease also, and it will not take the Finish Off if Wiped with a Clean Rag Right Away, or Washed.
Good Luck. KR Paul
