In any case, he said it usually amounts to somewhere between 10% and 15%.) He said he had the 42% tint available and it would typically wind up still keeping you *just* below the legal tint limit (at least for here in Maryland). Even if it went over due to combining with manufacturer's original window tinting, it would only be 1%-3% over. So not enough to call any attention to it.

Mine is Pearl White though, not black ... so not sure if that's helpful?
