I am aware of the slow load time of the forums. I am working in the background to resolve the issue.. I truly apologize for the issue and any other inconvenience this has caused/is causing.
Thank you for your patience. I will keep you updated.
My tint guy tells me it is second to the lights in the tints. He just told me that 5% is the darkest with 50% being the lightest. I have 35% on my windows. Hope that helps you out. Sorry it took so long to get back to you.
