I intend to install cockpit reefing/line handling on my steel VDS 34. However, the cabin ceiling is plywood lined without demountable panels, so to fix the deck organisers, clutches and winches, I will drill through the cabin tops and then cut holes in the ceilings to access the nuts for fixing. Does the panel have any thoughts on sealing the holes in the ceilings afterwards to make a tidy finish but remain easy to remove at a later date if I need to remove winches or clutches etc. I thought about plastic plugs but havent really seen any I think can do the job
