I have a 2010 370Z Black Nismo. Two years ago when I first got it, I made the mistake of wiping off my QD with cotton diapers, not realizing how soft the paint is, thus creating a new black car filled with swirls. I was able to correct this by using Meguir's Swirl X, applied with a foam applicator recommended by Auto Geek, and then used Chemical Guys 50/50 Carnuba Wax, again applied with a different type of foam applicator, recommended by Auto Geek. This was all done by hand, and dont quite recall the specifics of the foam pads other than one was red and one was white. The car turned out beautiful and swirl free. Being two years later, I felt it was time for a reapplication. This time I skimped on the applicator pads and used an Auto Zone cotton terry applicator pad. When I applied the swirl-x this time with the new pads and removed with microfiber towels, it seemed as if there were patches of haze when I looked at the paint from certain angles. Being a Dips**t, of course I forged on doing the whole car. Looking at it straight on, even with halogen lights, no haze was noted, but looking at a 45 or so degree angle those haze spots are easily visible and when I took the car into the sunshine, they are WAY visible, and not just patches, and it's almost as if there are now micro scratches. I tried applying the 50/50 wax to see if it would take out the haze, this time only trying one section (lesson learned) and didn't seem to help a whole lot. Has anyone experienced this? I am not sure if it all boils down to the terri cloth app pads or is it possible after 2 years the Meguirs swirl-x could have gone bad (I did shake bottle prior to use). And to followup, do you think I should use a more potent polish to correct what I likely have screwed up? Again I do this all by hand. Any suggestions on a good hand polish?
