I had the DW header pipes on my 100 wrapped with heat tape for about two =
years, then took it off and went to a reflective shield. I noticed no =
deterioration of the pipes when I changed over to the shield and that =
was ten years ago.

I don't believe that polishing is not the way to go as sometimes the =
process brings impurities to the surface and causes a lot of corrosion, =
esp. in SS. I have Jet-Hot coating or the like on the headers of all of =
my race cars and everything is intact and nice and shiny! =20

I'll add that, although I wrapped the mild steel downpipes on my BJ8 and =
have no problems--that I know of--I've become reluctant to recommend it. =
I've seen photographic evidence of pipes being severely eroded by =
wrapping; though it appears to be a hit-or-miss issue, and may be due, =
in part, to how they were wrapped and what they were wrapped with (I =
have to believe if it was a very common problem nobody would buy the =
wrap and companies would cease to sell it). I wouldn't expect ceramic =
coating to be a problem, at least if the pipes were coated both inside =
and outside (inside only might even be better).

Here in the colonies we mostly have to use gas with 10% ethanol ('pure' =
gas is available at some stations, but it's relatively rare). On a warm =
day, if my engine is hot and shut down for less than a couple hours and =
restarted I'll get some stumbling until air flow has cooled everything =
off a bit. I can't say with absolute certainty that the gasahol is the =
problem, but I don't recall this ever happening before the new =

might cure this problem.

Mirror polish them and leave them alone. Wrapping may lead to burning =
the metal away, coating possibly a similar story. By polishing you =
reduce the radiation of heat so the carbs should remain relatively cool. =
Anyway Webers/DellOrto's do not have the tendency to boil fuel. Also a =
car with an electric fuel pump does not normally have problems with fuel =
vapour lock.

What does the panel think?
See attached for a well researched synopsis. (Not by me!)
