| The biggest problem with these silicone sealers is when used near a carburettor,even the smallest amount of stray sealer can cause problems,there have been cases here in the UK where aircraft engines have stopped due to carb debris caused by silicone sealents,the sealent spreads out even within the flange and dries out as a small flap,then eventually it breaks off and can cause a blockage,with our model engines this is not life threatening,but it is just as well to be aware of the consequences of mis-application.
Used sensibly it can be of use in our hobby.
