I followed the instructions of spraying the wax on while the car is still wet (with excess water wiped off first). This wax does not behave like other spray waxes that I have used before. It feels grabby when wiped on. I think it is actually a good idea to spray it on a wet surface because of the "grabbiness". This is not a normal wipe on, wipe off product. After drying the car with this product, I could see smearing or streak mark appearing. I was like uh-oh...
Following the instructions, I then used another dry towel to buff the wax off. Buffing this wax off feels like buffing off a traditional wax. The towel felt grabby. After buffing the wax off, I was like wow! This wax seems to make the car shine more than other spray waxes I have used. The gloss is deep and the shine is excellent. The surface feels ultra slick, almost as slick as a traditional wax. I guess this is the reward for the extra buffing.
I then left the car outside after dressing the tires, sun-baking the car. The gloss became more pronounce after "curing". However, it started to rain after about 4 hours of application. I drove the car into the car porch and was amazed by the beading. Looking at the previous post here, the sealant on this car has become quite weak but this Express Wax managed not only to enhance the gloss but to create a good hydrophobic barrier. I am impressed.
As for durability, I do not know yet as this is my first time using this Express Wax but anything that can last a week or two is good by my standard.
Will I use this after every wash? No, because it takes some effort to buff off. I would continue to use other spray waxes after every wash and maybe use this once a month.
That's it. Happy detailing.
P/S: I was only planning to post this today but due to a great revelation, I ended up posting this and another post on the same day.
