on a blowing exhaust? Any good? will it hold for any length of time? Dont think it's a very big hole as it's not very loud, just a slight hiss

Yes, tried this on mild steel systems. Varying degrees of success, depending upon preparation of parent metal / removing surface scaling (rust!) , chemically cleaning metal before application ( using panel wipe / paint pre-prep solvents) and location of hole on the exhaust. Chemical Metal & similar products (often epoxy resin based) when set will probably not expand / contract @ the same rate as the metal they are "stuck" onto (will not be the same thickness either) . . . so the closer to the engine the quicker 1 will out expand the other and you lose the bond . . . My attempts at "repair" lasted several days to several months . . . but well worth a try to get you out of trouble.

Best to clean up & overlap the damaged area by a few centimetres, for extra grip.

You could try combining with exhaust repair bandage (if it's still available) to get a composite effect, a bit like fibreglass - but unlike fibreglass it won't catch fire . . .

Very difficult, I found, to fix the "PIPE INTO / OUT OF SILENCER BOX" type of repair, unless you fabricate a strip if something to support the joint, as when the vehicle moves along the road the exhaust moves about a fair bit and stresses the repaired area. (Probably why they fail in the 1st place)

Also, in an emergency you could combine using Epoxy metal with a cut up aluminium can (wrapped several times around the exhaust and a couple of stainless "jubilee" type clamps . . . as a get you home measure.

or for a dead cheap fix, use a bit of chewing gum!! it does work, the gum drys rock hard and blocks the hole right up.

Now that's just given me an idea for an attempt at blowing the world's biggest bubble-gum bubble . . . must remember to fill up @ T*sc*s & get sum clubcard points, too ! :-D Will deffo try gum next time though.

Thank you very much for the very useful and extensive reply. not sure where the hole is, just noticed it this evening so not had a chance to get under there yet, just remembered I have some of that chemical metal in the garage.. think I have some of that exhaust repair tape in there too so will have a look if it will come in useful too

Depending on the size of the hole, I've used exhaust paste (the stuff used to join the pipe sections) too which lasted a few weeks on a small hole:-)

Beer can, jubilee clips and exhaust paste works far, far better.

More fun too, cause you get to drink the beer first :)

bean tin works better still, the ribs squash around the putty real well.

(forherpleasure)

Yeah, but I don't like beans.

Why not use a proper exhaust bandage, its not exactly going to break the bank.

Loads of them on FLEABAY cheap enough
