Good to know

• How hot can it go? The facts given here state no temperature figure, so check the rating printed on the tube against the job before you use it next to an exhaust, turbo or engine casting.
• Can I use it as a gasket on an engine cover? Only if the tube's own instructions say so for that application; for oil-wetted flanges, a gasket maker that states oil and heat resistance is the safer pick.
• How do I prepare the surfaces? Clean off old gasket and sealant, degrease, let everything dry, lay a thin continuous bead and assemble before it skins.
• How soon can the engine run? Leave it the full 24 hour cure before it sees heat, pressure or fluids.
