Interesting.....wouldn't think of using it on my car as wrong thing for the job in my opinion.
Might work on grannys furniture but then grannys furniture tends to be indoors, dusted regularly and at best might get some food on it and if granny's would more than likely be covered in a table cloth.
So by that measure you'd need to drive your car with a car cover on it with holes cut out for the windows.
Granny's table doesn't have bird crap, tree sap, road dirt, salt, environmental fallout, lime, tar and other nasties to deal with....hence why Mr Sheen wouldn't be my first choice.
If it work for you.........c'est la vie
