What brand of silicone do you guys use? Personally I use GE 100% Silicone Sealant, and it works wonders for mod projects.
Red RTV 
It works well, but its annoying to apply, because its not exactly “flowable.” So its a lot harder for it to come out perfectly smooth, IMO.
Permatex flowable and blue RTV.
I like the copper high temp rtv. I also like the red. It lasts longer than flowable.
LocTite Clear Silicone.
perm. flowable for me too… it’s just too easy to use u can’t mess up…
Flowable, even though I don’t like it that much.
Red RTV here.
Permatex flowable for me as well.
Pioneer Black RTV Mighty Gasket.
It’s smell like a leftover, But people say when you smell it it’s cancerous, Is it true?
Red RTV ftw

Flowable.
