anti glare film

any of you guys with in-dash screens use anti glare film to cut down on the sun? I've played around with different angles but late afternoon sun washes out the screen on my eclipse avn4430

 

i haven't seen or heard of anyone doing it... i just went on a road trip and i just set my hat on the dash to cover it enough... if i went on more road trips i would consider something like this- removable and cheap!

i just ordered some film from the same company the army uses to supply their film for the electronics they use in humvees, abrams tanks, etc. I'll post some pics and review once I get it installed. If it works for the army in the desert, its gotta work for the afternoon sun on i-75 south!
