Cylinder / Barrel cleaning and in awkward spaces

[ukjules]

On bare aluminum do I really have to vapour blast the barrels ?

I can polish the side casings no problem but i get stuck on the barrels and fins.
Is it vapour blast and clear coat ?

I have yet found a tool that can attach to a drill and clean in any way
good enough ? Whats think ?
I want one bike to be perfect ! what the best way ?

vapour blast is the only way to get a perfect finish, imo. Do NOT clear coat afterwards, you will regret it.

does it not oxidise within a month though ?
How do you keep it in good condition ? as it is so awkward ?

I can do my own wheels from wrecked to perfect
simply by polishing and either leaving them to polish once a month
or clearcoat them.

vapour blasting is not a good key surface to spray anyway, and clearcoat will crack and flake off a head or block in no time and look awful.
I had my block,head and crankcases vapour blasted about 15 years ago and after a regular wash with hot soapy water they still look almost as good as the day they were done.
Not sure if all vapour blasters use it but when i had mine done, the solution they used included an anti oxidisation chemical which gets ingrained into the aluminium

Do you hand polish (sand down etc) your side casings etc and only
vapour balst central casings and barrels ?
