right. u had factory tint and then re-tinted with aftermarket....hmmmm, crap Mine may be slightly darker then legal, I forgot about the factory tint my GP came with lol
if u put the meter on a stock window with no tint it will read about 95% to 90% (blocks 5% to 10% )light getting through, sooo 20 - 7 = 13%
