Thank's for all the info guy's. I was going to use 5/8 just because I was told it was better for the ceiling I really didn't know. I have been discussing with the "project manager's" about getting some one in on a quick cash job to tape it. It is a small room about 16x12 and what would take me 3-4 day's with so-so result's could be knocked out in 2 with out all the extra dust from sanding. Sorry about no new pic's but this project seem's to lead to another and not much progress has been made. Example just rained Sun 1st time since we gutted the place while working last night I noticed a puddle on the floor found it was came from the vent for the plumbing instead of putting up vent flashing the previous owner's just gooped tar around it and now it leak's but this one will be farmed out and done right cause if it leak's again there will be a brand new kitchen with new water mark's to go with it.
