Turtle Wax Hard Shell is a truly horrible wax. It was the first wax that I used since I began detailing. At first, I didn't know better, but then found that there were so many waxes that have better quality for the money.
Here's why I didn't like it: The application was so-so, a bit dry for my liking, but it worked. However, removing the wax was IMPOSSIBLE! I tried extremely thin applications, but it didn't make it any easier. Since it was so hard to remove, you and I would have thought that the durability must be unbeatable... But it only lasted 2-3 weeks maximum outside, not garaged. The shine was mediocore, definitely better than an unwaxed car, but the removal process is highly inefficient and will easily scratch the car if you are not careful.
If I were you, I would consider some other waxes. If you don't wish to order online, there are many good waxes that can be bought over-the-counter for reasonable prices. I'll list some products that you can do some research on: Mothers Carnauba Cleaner Wax (Easy removal, although 2-3 weeks durability),
Meguiars Gold Class Wax (Similar to Mothers Carnauba),
Meguiars NXT Wax (Synthetic, lasts slightly longer, very nice shine), Collinite 845 (4-5
months durabilty, very nice shine, used by many), Duragloss (haven't used it before, have heard really good stuff about it), Turtle Wax Platinum Ultra Gloss (MUCH better than Turtle Wax Hard Shell, considered as a high end Turtle Wax product, gives great shine, mediocre durability).
I have never heard of the Polish 2001, but since it's not very popular, I'm going to assume that it's not
that good. For oxidation removal, I would go with Meguiars ColorX,
Klasse AIO, or Jeff's Werkstatt Prime and Acrylic Jett. Those are all very good oxidation removal products. I personally use ColorX since it is sold OTC, no online order needed. It does a good job of restoring color and gloss and can be used as an
all-in-one which polishes, and protects in one step. The durability, however, is not that good (usually polishes aren't designed for protection but rather cleaning/polishing), and should be layered with a pure wax such as Collinite.
Hope this advice helps you in finding the product that best fits you and your car. Welcome to autopia!
