Ceramic coating and a helmholz resonator?
 

I haven't been able to find any info on this, so hopefully I'm not blind.

I'm about to get my Nameless over/front pipe ceramic coated but I'm not sure about the helmholtz resonator. Should it be coated? Or will the coating affect helmholtzs ability to eliminate the resonance?

Maybe @Jason@Nameless might be able to shed some light on my question?

Thanks in advance!

Zero impact on the function of the resonator.
