I've been messing with cars for about 30 years now and I've tried a lot of waxes etc. I have had 5 Star Shine on two cars now and I couldn't be happier. I first put it on a BMW 330ci about 3 years ago. At the time, 5 Star said that after it was applied, you could just hose the car off and dry it. The PTFE is so slick that nothing sticks to it. Well, I couldn't bear the thought of not soaping my precious BMW so I would wash conventionally with a dilute solution of car wash soap in water. But every time I washed, the wash water never got dirty! The wash rag just didn't pick-up any dirt, because there wasn't any on the car. So now the GTI has 5 Star Shine (BMW's been sold) and I just hose off, water squeege, and dry with microfiber towels. Looks Awesome! And no more waxing!
I recommend rubbing the paint out thoroughly (by hand or buffer) with a quality polish or extra fine rubbing compound from a paint shop before applying 5 Star, to be sure the paint is as clean and smooth as it can be. The 5 Star isn't a cleaner. Also, if you want a 3M/xpel type clear bra (they are great, check out Starshieldarmor.com, they can refer you to an experienced installer in your area) put the bra on the car before the 5 Star. The bra may not stick to the 5 Star. Apply 5 star right over the bra.
