Just wondering if anyone has had any experience with the Nightshades tail light tint stuff? I believe I'm gonna tint my tails and also maybe the red marker lights behind the rear tires. This stuff pretty easily applied and is there any prep work other than cleaning? I see it says 2-3 coats should be sufficient. Would you recommend using a clear coat and which VHT clear should I purchase. They have clear for brakes, engines, etc and does it matter which one I would need? Thanks for the help guys.
