Marx generator caps?

hi, i am building a marx generator and wondering if these caps would be suitable. i am going to run it off an ignition coil circuit with an output of about 10kv and no more than 2 milliamps. would these be good to use?

thanks

ok, i have found out that the input voltage should not exceed the rating of the caps so i can lower the 10 kv to a lower voltage. also would an ignition coil work with a marx generator?

sorry for posting this, i have found a site for this type of stuff so if you want you can delete this post
