so i just got my cylinder back from the machine shop..long story short while carrying it, i tripped and cylinder fell on some tool had couple gouges...is this still good or do i have to get it machined agian...also would i get away with spraying copper coating on? help please

 

how deep?

 

i could feel it with my finger nail

 

I'd get it skimmed again just to take off the high spots. Take it to your machinist and let him make the call.
Be careful.

 

x2 better to do it now then have to pull the motor apart again and buy a new head gasket
