That stuff is VERY heavy. The best thing I have found for "heel guards" thin stainless steel patches. It is also preferable to have something that the heel slides on.
I used the cheapo rattle can version on my rudder pedals. It was fine after a few weeks of getting cured well.
If I were to do it again I'd have them sprayed with real truck bed liner... the kind with lil bits of shredded tire.
Have you flown with “non-skid” on your rudder pedals yet? I don’t think I’d want to do that as I routinely slide my feet up and down to get on and off brakes. I don't think I have ever flown an airplane where the pedals didn’t allow you to slide your feet freely.... your mileage may vary of course...

I was thinking Titanium patch. Light. Thoughts?
In floatplanes and airboats its where I got the idea from. It doesn't stop you from sliding your feet if you want to but it does keep your feet from sliding if you're applying brake pressure. Wet feet + flat metal rudder pedal = sliding feet.
