Engine Blast

[Neo7]

Hi all,
I'm currently rebuilding a 25HP V-Twin and before I put it all back together I want the case and cylinder cooling fins to be clean and bright aluminium.
So I was wondering if anyone has shot, sand or glass blasted their V-Twin case before and what type of aggregate did you use for best results?

Many thanks.

Aluminum will still oxidize back to a duller finish.

Oh Ok thank. ... so I'm kinda wasting my time then :-(

So what's your thoughts on spraying the cylinder heads fins and rocker cover cans with black engine enamel?... Would that help with heat dissipation?

No. It will insulate the fins causing poor cooling and over heating. Not a good idea.

I've used light coats of aluminum paint with great results.

Visually yes, bet it looked like a new baby calf.

Thermally, no. All it did was mummy wrap the cooling fins killing cooling performance. Doesn't matter it if was silver or copper paint. Paint in itself encases things like a warm coat in winter. Think about it.
