Default Re: Best oil-proof sealant?

No, it doesn't need temperature to 'cure' it. I've used it on the washing machine connectors for the cold feed, which are only supposed to be hand-tight. Hard to get them to seal if only hand-tight, but no problems when the Blue stuff is there. When it comes out of the tube it is fairly fluid, but quickly begins to dry out and firm up, a lot like Evostick glue. You only need a thin even film, I'd say on both surfaces, and just let it dry to the point of 'tackyness', then mate things up; try get it lined up at the first go. Ideally, give it 24 hours to really get the best outcome before you stress it.

As Boater says, it was originally developed for cylinder heads, so it needed to be good with both water and petro-chemicals at significant temperatures and pressures. Buy some and play with it.
