When I got my new Prius recently I was still a caveman and didn't know much about paint care. I got some TurtleWax and Meguiar's Gold Class Wax, washed the car with some generic car soap and coated the paint with 3 x TW, then 2 x Meg in the space of 2 days. The finish felt slick and looked glossy, and lasted about a week!
So I went surfing and came upon this website, and after getting through the info overload I narrowed down to DG. Zaino has lots of supporters but I decided it was too expensive for me, whereas DG looked like good value and also has good testimonies here. I emailed DG and Jerry got back to me quickly, recommending the 601/111 combo since my paint is new. I ordered these and DG even included samples of AquaWax and the DG car wash concentrate (thanks DG, excellent CS).
I read about claybars here too, so I got the ClayMagic and clayed the car even though it didn't feel like there were any roughness. After washing with Palmolive to get rid of the TW and Meg, I applied the 601. It went really smoothly and dried pretty quickly. I then applied 111 and that went on and wiped off easily, leaving a really glossy finish. I waited 24 hours and applied another coat of 111, then a third after another day. The third application seems like it did less, probably because 2 coats of 111 is more than enough. The finish was glossy but not as slick as the TW/Meg combo, until I decided to try the AW. The AW made all the difference, it gave a supersmooth, slick finish and went on super-easy. All the above were applied by hand only.
The 601/111/AW combo made me a DG convert, still waiting to see about durability but so far so good, it's been about 3 weeks. So thanks DG, and thanks Autopia for all the useful info. Good to see a website that has no bickering, just sharing of information and experience.
