in maryland the limit is 35% and I had that too. you might try to clean your windows but also, if you live in the county and not the city, county inspectors are going to be more picky than those in teh city. I had problems iwth my front headlights not being stock lights, and an inspector in the county failed me, i went to the city, I told them that I wasn't selling the car, I was buying it (which makes a difference) and I wasn't trying to swap out the lights and take 4 hours of my day. He let me slide, my advice, go to the city.
