Krown and factory frame warranty

I thought they fixed the frame rot issues for the 3rd Gen?
This is the first in hearing about them.

Regardless the CRC coating is more like a rubber paint of sorts if it's the same as the 2nd Gen.

That said it's a one time thing because it's meant to be more permanent.
Vs krown done yearly because it comes off.
It's just an oil coating to help prevent rust that comes off.

 

There are different grades of powder, FYI.
