Greetings fellow Shelby owners. I just bought a used 2011 Shelby GT 500, Kona Blue. I washed it the next day and used MacQuires scratch remover wax to buff out a few surface scratches. The bummer is that I noticed some small swirl marks left behind as a result. I know I can buff out the swirl marks with a different product but not sure which one. I have a friend who is a local county police officer and uses IBIZ on his cruiser (charger). He swears by IBIZ and offered to help me wash and wax the Shelby. His cruiser looks immaculate, but I wanted to research before using a product that might ruin my paint job. So what do you folks recommend. I don't want to spend 8 hours waxing my car, but want a great shine. Thoughts? Thanks much for your advice!
