I was getting sick of the Klasse vs. Blackfire debate, so I tried both together to see if they work synergisticaly. They do! After prepping I first applied AIO, followed by Blackfire protectant and topped with P21s. Fantastic combination! No smearing or hazing, and on my black truck it turns heads. All three products are super easy to apply and remove and combine the benefits of all three products. I personally don't like SG on black, it makes it look brown in the sun. This combination makes my truck as dark as a black hole. Give it a try!
