I have used it and still do. Used on my ‘03 Blackbird, ‘17 FJR both black. Just applied it to ‘18 blue MT. Nice deep gloss on all of them. Biggest advantage is how easy it is to apply and wipe off. I still use Maguires if the finish gets a scuff.
Id recommend the last coat for a long life coat with deep gloss, or the P&S Beadmaker for shorter lived but breathtaking finish.
A ceramic coat might also be in your interest. Carpro have great DIY ceramic coatings, which still last for 2 years, unlike the professional ones with 7 year warranty. Add a sealant on a ceramic coating every month or so and you are golden. Easy to clean, great durability, incredible water beading and sheeting and intense finish.
I applied Carpro Dlux on my rims. Water and a spray with my foam cannon takes the majority of dirt off, if i want a spotless wash, just car shampoo and a soft brush makes them look like they just got out from the painter.
Its a ceramic coating so application is a bit dofferent and more involved. Tutorials are recommended.
The negative reviews are thypical for ceramic coatings if you just go into it with waxing in mind, get some knowledge on the stuff and how it should be applied and youll be fine.
Have had it on for 7 months by now and have not experienced anything bad about the product.
Thypically for ceramic coats, the flaking is if the surface was not completely spotless (clay bar, iron fallout remover, mild IPA) when applying and applying a too thick coat, not buffing it out well enough
