How come its only the head if you sprayed it on the whole engine? As far as I can tell, heat will spread through out all the parts.I cleaned it with muc off cleaner then added the protector. I did a Google and there's a suggestion the cleaner is slightly caustic which would maybe explain it.
I wouldn't have expected it to change so drastically after 1 use, or at all given its meant for bikes. It's also odd the block looks fine!
I will go take another look later and hope it's maybe caked on residue. You live and learn!
