Hi all,
Some may recognise my posts. I'm slowly doing up a 78 Daimler Double Six
As previously mentioned the engine bay was in appalling condition. Progress is glacial but steady, I'm still not sure what I have let myself in for.
I have been working on the inlet manifolds which I guess are the most visible and striking feature of the engine. They now look like new. I was wondering if anyone has tried applying a light coating of clear engine enamel onto the bright aluminium castings to retain their appearance and prevent oxidisation?
al
but prevents the oxidation or rust issues. go with a high quality, hi-temp product and your yellowing issues may be minimized.
Personally I prefer a slight yellowing over the oxidation on the aluminum pieces and the rust on the steel parts.
I'm getting my intake/exhaust manifolds and a few other things redone in chrome-like thermal coating. Reduced heat, increased HP and a sharp look. Good up to 1400F and much more resistant to damage then bare metal.
Spend the $200 and find a shop that does thermal coatings like that.
then inlet manifolds EXTRUDE HONED, very smooth and takes out the internal humps and bumps, injector protrusions, also opened up 1/8th inch alway thru, including the plenums!
outside painted RED, fins smoothed off for visual effect!
24yrs later , still looking good, better resolution also!

exhaust manifolds ,1st ported & smoothed internally,then Ceramic thermal coated.
