Hard anno? ... or not! as the case may be :-)

ED209:
I've got some Primo cranks.

Not painted as Synstrip won't touch them.

Not normal anno as Oven Pride won't touch it.

I know you can get 'Hard Anno' ... so what will shift that?

I bought a bullseye powerdisc a while back that was hard anno. Neither oven pride or super strog caustic soda would touch it. I was getting it re-chromed anyway, but thought i'd do the prep/polishing to save time and money with the chromer. In the end i had to get hockley chrome to strip it and then prep and chrome it. Might be worth giving them a quick call if nobody else can help you out. Might either be acid or some kind of reverse electrolysis method to sort it out. If you need to contact Hockley, ask for Lee  :daumenhoch:

I think there was a head gasket stripper that shifted it? Don't wander off and leave it or your cranks will be a blob of disolved alloy though..... :shocked:
