F2 Engine coating removal ?

(1/4) > >>

Grewth:
Today, I have acquired a CB750F2, 1978 vintage.
It was cheap.
For a good reason,  it's a total wreck.
47 years of British weather have not been kind to the black coating that Honda applied to the engine unit, it's festering and lifting off in places, and TBH, I think natural alloy looks much better anyway.
From my experience with Yamaha's,  it's an absolute pig to get off.
I'd be interested to know if anyone has successfully stripped an F2 engine back to bare alloy with a presentable finish  ?

Forgot the photo

Bryanj:
oooh PD carbs with pods have fun with those.

as to the black coating how about nitro-glycerine?

royhall:
When I did mine it had to be bead blasted as nothing else would shift it. But mine was being repainted so the bare metal finish was not an issue. That finish is as tough as old boots to shift, even the bead blaster guy was complaining about how long it took. If your building a special, convert your carbs to K model units as those PD's are a royal pain to get right.

Laverdaroo:
This was the result of vapour blasting and then clear corrector over the top. I think it looks ace but each to their own.
