I know this is an old thread, and people have pretty much concluded that 5 Star Shine is nothing special, but I just wanted to add my thoughts on the product.
Over a year ago, we treated my Mom's Galaxy Silver 2003 Impala LS Sport with the 5 Star Shine. It gave the finish a deep shine and wonderful brilliance. The product has held up very well, and dirt just sildes off the car when it is run through the touchless LaserWash machine at the gas station. We have not had to wax the car since the 5 Star Shine was applied.
I just treated my Bright Silver 2003 Dodge Durango today with a 5 Star Shine kit. It is not the easiest product in the world to work with, but it definitely leaves a hard, slick protectant on the paint. Total time to apply the product was 3 hours. I agree it is not a 1 hour job as advertised. I washed the vehicle with standard Eagle One Car Wash, followed up with the wash in the kit, let the 5 Star wash dry to a haze, rinsed the vehicle and then dried it completely with a chamois. I then applied the 5 Star protectant.
The protectant goes on much like a standard commercial liquid wax (Nu Finish, Meguiars, etc.) It does, however, dry VERY quickly. If you let it sit too long on the vehicle it becomes hard to wipe off (it has now been a few hours since I completed the task and I can feel myself getting sore). A thin application is the best route. I was concerned during the process that I would not have enough to complete the Durango but I ultmately finished with a little of the protectant left in the bottle.
I am relatively pleased with the results on the Durango, but the finish is not as brilliant as after we applied it to my Mom's Impala. Perhaps the shine will increase over the next couple of days as it indicates on the bottle. Tomorrow we are forecast to receive heavy rain and thunderstorms, so that will be the true test of the product. I would expect it to bead up very well.
Would I recommend the product? I may suggest it as an option for people to consider but I would not go out of my way to say to people "this is the best suff ever...you won't regret it!". My opinion may change depending on how it holds up on the Durango. I bought it based on the great results my Mom had with it on her car, but I am not sure the results will be as good on my truck.
Is it worth $65-$70? Maybe, maybe not. $30-$40 would be a more reasonable price. Again, I paid the price based on the great results on the Impala.
My Dad is picking up his 2005 Subaru Outback tomorrow. He was thinking of using the 5 Star Shine on it, but I may direct him toward the Simoniz System 5 treatment. I have heard good things about it and many dealers in this area have started offering it as well. It can also be had for 1/2 the price of the 5 Star Shine system.
