So I have c2v3 and find its longevity to be average at best, despite IPA wipedowns, paint cleanser wipe downs etc.
I kinda figured that, being so cheap, it was essentially an alternative to a QD with enhanced protection, akin to dodo red mist etc, rather than a hardcore protection option.
If you prepped the zed, applied exo or crystal lacquer etc, I'd expect super longevity. I'd then use c2v3 to top it up after maintenance washing
