HAHA. I bought a bottle of that about a year and a half ago when i didnt know the proper way to detail. It has a place in my regimen now for hazed headlights. Thats the only reason I have that stuff anymore. The consistancy is puke. Literally it looks like puke. I wouldnt advise use on paint being it is very gritty. As for the manufactorers claims of 1 step shine. Probabaly Not.
I've used it satisfactorily enough to be willing to have some around for neglected and weathered paint jobs, but there are some cases where it won't produce a shine.
