Re-coating worn tips

The tips of my most loved foil have been sanded down over time. What’s the best way to build up a protective layer so that it doesn’t get down to the fibers? I was thinking about using an epoxy spray paint but wondering if theres a better way or a preferred mixture or brand to look out for.

Clear matte spray paint is my go to

I use spray lacquer, which dries in a minute, and can be built up over multiple coats. Seems to work well…
