Huh, never thought of Nitro-Seal as being more durable for some reason.
I'm trying to be open minded

The other 3D stuff I've tried (admitedly a short list

) has sure been great, but I've just been so enamored of FK1000P that I haven't been considering other LSPs. I mean... FK1000P is lasting well over a year for me even on (winter-use) daily drivers; I've never used anything like it and that's saying something (not even 6X KSG can compare IME). I don't even bother cleaning off bird-bombs much any more.
I hear you on the look though, wouldn't do the "deeper" thing. Might be kinda an acquired taste, at least on certain colors, and not everybody will like its "signature look".
