Is there a recommended process to coat the inside case of a blower  
that has been scored?

John,

When I was in the Navy we used to repair eroded high pressure sea valves 
(submarine type) repaired by using a product called Belzona.  It was 
applied, machined off and the valves were as good as new.

How deeply has it been scored?  If you're using it on an XPAG you may be 
able to get by with just having it skim cut by your machinist...you'll lose 
a little pressure but not much.

John, 

I would try to contact George Folchi, one the recognized Judson gurus to see
what he thinks.  Even though you may not have a Judson, I think the answer
would apply.

Interesting range of products!

Just had to share this "case study" I found ... They have some very
interesting manholes in Slovenia!

I couldn't find one. If you are talking about a Shorrocks, then one 
thing I have noted is people claiming that  under high-speed the vanes 
and the case come into contact, and the interior of the case gets shaved 
out a hair in the process. If that's true, then you should steer clear 
of extremely hard coatings, as that would cause vane wear.
