I bought a rear window protector (tube) from Coastal metals for my new
S2000. I placed it across the rear window before lowering it. A few days
later I raised the top and noticed the hole pattern from the tube had
imprinted itself on the window. It appears to have almost heat stamped the
pattern to the window. Any suggestions?

 

Leave it out in the sun. Another trick is a hair dryer but be careful not to burn it.
