Carburettor flange and water flange seal with Hylomar?

Hello, I have a problem with the rear water connection to my ABT engine. It just doesn’t want to get tight. Although I have already used a new flange including new seal. Nevertheless, there is always some water out there and I want to ask if you can possibly use Hylomar for it. I also have some problems with the carburettor flange. So not the lower one. But with the paper seal that is in between, it is also not quite as dense. I would have to be able to use the rest of the Hylomar without any problems, right? How do I use Hylomar correctly? Both sides lubricate in? Although at the back of the engine, this is going to be damn difficult.
