I have only done corn with husk, but I peal the corn husk layer by layer until you can remove all of the silk, after that put the corn ear down in a pot of cold water to soak for around 2 hours. Pat the corn dry and add a coat of olive oil with salt and pepper, or do a butter mixture of your choice and pull the husk back down. Secure the end with a twist tie, string, or wire of sorts. Cook times depend on temp, but at 225-250 anywhere from 1.5-2 hours.
If you do a full dozen make it a few different ways to see what works best for you.
