I have 30% sides, and 5% rear glass (bought it with that tint). I do not really like the contrast, and have been for a while wanting to tint the sides to something darker, like under 20%. I have been discouraged though due to the added cost to remove the current tint. But then I saw someone post elsewhere about "double tint", which apparently is a thing people do. Anyone have any experience with this. If it’s even possibly going to look like shit I don’t want to do it, but if not, I would like to do it.
