Looks really good.
Not a criticism, just an observation and curious question. Why not remove the rails before painting?
Mainly because its a royal pain in the arse to do at the best of times!!
Though i WILL remove rails on a game if i have to for any reason, usually because it just makes it simpler when making stencils on some games.. some 70s Bally games come to mind, eg 6million$man or Silverball Mania are two that i resprayed that i removed the rails on. Oh and Stern Dracula it was necessary to remove them.
