I am anal about shinning and polishing. I honestly enjoy it and love the results. Whether it is the garage floor, the muffler or the car's paint.... love to shine it up.
Over the years I have tried numerous waxes and settled on One Grand Blitz Carnauba as my go to wax for the cars. It is a great wax. Every now and then I would also use P21S Concours Look Carnauba. At times (rarely) One Grand Blitz would fog on the paint and the P21S was great for fixing things up.
Then.... I read about P21S 100% Carnauba Wax. It sounded good so I figured I would give it a shot. I wax the my Guards Red Boxster at least once a month. After 14 years I had the typical light spider webbing on the paint that was visible in the sunlight. After several waxing with the P21S 100% Carnauba Wax my paint is perfect without any viable spider webbing. The paint looks amazing. I am guessing that this would work on black cars too.
I usually don't recommend products like this... but this one deserves a shout out. It does cost about 37% more than the standard P21S wax and $60 for a 6.2 ounce jar isn't cheap. But for me it is well worth it. It appears you can get over ten waxings on the Boxster per jar.
