Painting The exterior of a 97 lx450 with 14L of raptor bedliner, hopefully don’t use it all but that’s not the point. Contacted all my local paint shops here in Colorado and they refuse to do a custom urethane tint... So sticking to 3oz custom coat from amazon, has anyone tried mixing any of their tint concentrates? I’m looking to get an off-white and was thinking 90% GM White and 10% frost beige? Anyone with knowledge or experience?
