I think before a Sharpee- which is permanent....
I'll try a Vis a Vis- water based pen- used them in my classroom overhead.....
and if I can remember to bring my camera out...and shoot a before and after pictures...
Sunglasses I wear right now are not polarized....may have to invest in a pair to see if
that helps...alot of people have mentioned that suggestion.....

Polarized sunglasses are great. Especially if you do a lot of driving. I just recently got a pair of prescription sunglasses that are polarized. They make a huge difference to the amount of glare from a hazy windshield, glare from a shiny dash, and reflection from other cars. One thing I noticed about mine is that I see a weird checkerboard pattern on some windows. I usually see it in the rear windows of cars, and the side windows of my parents' Impala.

Gearhead nailed it......
 

Problem with the Lacrosee is "veiling glare"!

A member named Gearhead....hit it right on the nail.....Shadows and ghosts are caused by
veiling glare!
