Re: increasing exhaust/muffler life-span: durable finish?

[Theo Thepen <thepen@pi.net>]

Hi,
I had both the exhaust and all four heat exchangers sandblasted and then 
Zinc plated. This was not done by dipping, but by spraying. I haven't 
got a clue asto what the proper english word for that is. It's not paint 
but they spray melted zinc (FLAME SPRAYING??) on the bare metal. After 
that they were sprayed with heat (>600 C) resistant paint. This was done 
a year ago and they still look great. No rust, at least on the outside, 
and no pealing of the paint. Rust from the inside is only a major 
problem if you drive short distances and only for the exhaust because of 
the fumes. The heat exchangers won't rust from the inside unless you 
keep the car outside in moisty conditions. My notchback sleeps in a 
warm garage, the KG34 is in a heated storage. For me, every heat 
exchanger or exhaust I see, I buy. Especially the early type exhaust 
with the small het exchangers intergrated, they are very hard to come 
by. I've got a good collection at the moment and no, I don't sell them, 
sorry.
Cheers,
Theo
