Any brand will work. The self healing will still be there but you're missing the crux of the ceramic. It deposits a few microns thick layer of sio2 essentially glass on top of the surface. So if the ceramic is scratched off you'll have to reapply after prepping that area. Whatever self healing won't be healing cuz there's a layer of sio2 on top. But if a scratch gets thru the ceramic, the PPF is there to protect the part and then do it's self healing thing.
