Hi all , We are renovating a 1959 feadship , we currently mainly live on board . Our disel tank is huge and we want to block one of its sections . I am attaching a picture , I thought of cutting a 3 mm metal ( or plexiglass) and to glue it with special sika flex so it is sealed , my worry is the lower part where we have a circle hole in the button. 1. What do you think better putting metal or plexiglass 2. Any other tips ?
