You are overthinking it. An 870 is not tightly fit enough for a park coating to affect function. No need to remove the shell latches for refinishing unless they're worn/damaged. Cerakote should be applied in thin coats. You do not need a high build to get a good finish. In fact it will be less durable. If you do decide to do it later over your park, be sure to thoroughly degrease. Better to do it over fresh park.
