Internal silencer painting

(1/3) > >>

Grewth:
I've just bought a new set of Busso exhausts from DSS.
Who makes a paint system for coating the inside of the silencers  ?
I've seen something "specialist" advertised somewhere,  but I can't remember what or who sold it.
I generally try to avoid "top dollar" automotive products, but in this case the exhaust system was over £1300, so maybe using something expensive would be justified.

SumpMagnet:
I used to throw some 2 stroke oil through it. Burns off in the pipe and leaves a residue. No idea if it helped, but I figured anything that would cover the internals would help to keep condensation off.

TrickyMicky:
Try and make it a golden rule NOT to start the engine unless you are going to get it nice and hot. I paid the price in the 1970's on my 750, silencers rotted through in 14 months. Of course with 4 separate pipes and a large engine you are going to need some decent length journeys to achieve this. Even on my 400 I follow this regime, and I'm still running an OE system which I fitted in 2006. Merry Xmas to one and all.

This was the way I used to do it way back in the 70's

Grewth:
Nobody ever heard of any sort of internal coating system then  ?
Apart from oil that is.
I'm sure I saw something about using a paint "wand" to spray the internals of the silencers.
Basically this was just a length of plastic pipe attached to a stick, with a 360° spray nozzle on the end.
Trouble is,  I can't remember exactly where I saw it.
