Ok so I know the main difference is that NFS has protection in it... it says they both have mild abrasives. is that it? Is one better than the other?
NFS is carnauba based so you wouldn't want to use it expecting to layer a sealant over it. I would think there would be bonding issues. The one time I used it I just put a wax over it.
Its kinda like KAIO but carnauba based. Longevity is pretty lacking so you would want to top it with a carnauba. Lime Prime is a cleaner prep for putting a carnauba on.
