I'm trying to help out a non-mechanically minded friend.
Does anybody have current knowledge of metal spraying and its effectiveness?
I've looked on the web but personal experience and recommendation would be useful.
Many years ago I knew of it being done to a motorcycle crankshaft. In this case it is for the crankshaft of a high performance car where the big end bearings are undersize, below regrind tolerance.
Thanks.
