Since you won't reveal how you are going to deal with the rotor
housing wear surface I give you a snow balls chance in hell
of surviving. In that case it smells like nothing more than a scam.
I would wait until some other sucker buys hundreds of engines
from you and run them to 1000 hours before I would shell out any money.

Is this clear enough for you or do you want to know how I really feel? :)

Paul,
On a less emotive level, advice to me from those in the know, suggest that
many surface coatings are very good and wear very well - HOWEVER the
surface, no matter how hard or how good is dependent of a good SUBSTRATE,
because of the substrate compresses/ flexes the surface materials goes with
it and will surely fail!
Aluminum by it's very nature is a soft substrate and does not meet the
requirements to support a very thin hard surface, steel does, so the fully
lined steel hard chromed liner is ideal. The det-gun coating are only half
way there as the hardened material penetrates only so far.

This explanation to me satisfied my questions as to why thin surface
coatings - no matter how good- failed. I hope it helps other to understand.

Well put George except for the emotive part :)
