HPC coated stainless steel headers, how tough are they?

I have HPC coated stainless steel headers. I accidentally sprayed Loctitie Extend rust treatment on a part of them. Well, I then started the car and ran it , not knowing it was there as it was clear. but when I came home I opened the hood and noticed a brown varnish looking stain on the headers. Do you think the stainless and HPC coating will get ruined because of this?

I drove the car around for a while, and it never burned off, so I guess it stained the coating. HPC said it "may" cause problems later, but I think that is/was a safe answer from them.
