High Temperature Exhaust Sealant Paste — 75 g to 225 g

Heat-resistant paste for sealing exhaust joints and small blow-holes in a muffler or downpipe — the fix that buys you months before a proper weld.

What you get

• High temperature formula — stays put where ordinary sealant burns off.
• Three sizes — 75 g, 150 g and 225 g, plus 3-packs.
• Cars and motorcycles.

Worth knowing before you buy

This seals joints and pinholes. It will not bridge a large rust hole or hold a broken pipe together — that needs welding or a new section. Apply it to a cold, wire-brushed, degreased surface and let it cure fully before running the engine, or it simply blows out.
