I took the dollar store test with my FMU and in the alotted time I saw what almost looked like a dent where the positive line goes. It was the same width as the control line but it was virtually white. Can an evap line show up in the first 3 min? I am really confused. I called the number on the box and the guy said that if it was negative there should be NOTHING to see. I told him it was colorless or if ANY color possibly grey. He said it probably meant I was borderline and if I test in a few days it will start to get darker. This doesn't sound right to me though.
