Perm said:So the question is...... what is the test to confirm that paint work is still being protected other than beading ?
I was told after washing the car and making sure its dry. Take a MF towel and throw it across the hood. If its still protected it should glide accross relatively easy. That the hard part what is realatively easy. By the looks of this picture it about time to rewax, but there still is protection. BTW was that car garaged or outside 24/7.
