Rusty exhaust

[jezmilligan]

Oh dear - the middle section of my exhaust is starting to look a little rusty.  Anyone know any treatments/protective coatings that can be used which will stand the heat?

Camcoat

That reminds me..........I must give 'em a ring, see how my exhaust is getting on...........

Thanks Blatman - looks good and not expensive - I'll have to get it done next year.  

I'm looking for something more immediate right now though - hopefully something I can just paint on to remove the rust and protect the exhaust?

In that case, remove as much rust as possible with a wire brush and maybe a flap wheel in a drill or a wire brush equipped bench grinder. Then heat the section with a blow torch, and spray on some Hycote exhaust paint (available from Halfords). Apply 3 or 4 thin-ish coats while the piece is still hot. Don't be afraid to re-apply heat between coats, you won't do it any harm.

When you re-assemble, use copperslip in the joining faces as a token effort against it rusting solid, and so that you don't need to cut it off when you come to dis-assemble it in the future.

Me, I'd suffer a week of the car being in bits and get it camcoated sooner rather than later.

Thanks - I'll give it a go this weekend.
