I was looking at this for my denim black as well due to the fact you cant wax to protect the finish. I will look forward to others experience here.

 

I understand your concerns. How many magic products have we seen over the years . Seem to work then have a serious down side. I am always interested but will take a wait and see on it.
I have used Zaino's for years . It is one of those magic polishes that works . But like you say it can be washed off. I will be looking for more real information on F11. But not from some youtube video. Same with post in forums like this often the post about the product is a set up for sales.

 

I ended up using mothers back to black with no ill side effects. It does wash off with a few washings but it looks good after applying.

 

My bike has been treated with top coat , the bugs are still a bitch to get off and the rain still leaves the bike filthy.
I can get the same results out of Lucas Slick Mist from auto zone for $9.99 a bottle. In my opinion, top coat is not worth the money.

 

I made a purchased of the product and have tested it on my black denim and yes it has restored the bike to looking like new. You can see all the videos on YouTube as well on applications done on several bikes. The product is not cheap or rather you don't get much for the buck, but then again you don't have to use it as often like other products. I think that it works well with the black denim and I also used it on the wheels and chrome. I give it 4 👍🏾 up.

 

I also use back to black and it's great

 

Do you have or ever use Polycracker? A must for removing stubborn surface contamination or coatings before prepping for refinishing.

 

Mine arrived today. I'm probably a sucker for buying it... Couldn't stop myself.
I think I'll test it on the neighbors car first

 

That was good for a laugh first thing in the morning. Let us know how it works out. A lot of us have gotten the spam on facebook and would like some real world feedback.

 

I ordered some myself. At first I wasn't that impressed. I ordered their starter set, came with a 16 oz bottle, plus a travel sample, and two premium microfibers. The microfibers were nothing more than Walmart brand, and I have way better "premium" microfibers that I've ordered over the years. I washed the bike first, applied the sealant, let it sit for a few minutes, and wiped it off. I will say it left the paint very smooth and slick. I'll be more impressed if the bugs and dirt won't stick to it, but no chance of riding around here for a while. I guess we'll see, I might be a sucker too for this.
