I use this stuff in an orange bottle called Nufinish.
I've been using it now for close to 40 years. I've used it on cars, motorbikes, boats, aircraft, RVs, firearms, cabinetry, helmets, just about anything that has a smooth surface and needs protection from the elements or rough handing or what have you.
It may not be the best anymore, if it ever was, but I've never been disappointed in the performance.
