Post by: MartyC on April 03, 2014, 11:29 AM: Sugino CT cranks are 4130 Cro Moly so are not annodised. Did you mean Sugino GT?

What colour were they before? Ovenpride can sometimes turn the alloy a blackish colour due to the contaminants on the alloy surface, it should polish off.

Post by: Snav on April 03, 2014, 12:33 PM: If they have been left Black surely there is No anno on there ???

That discolouration only normally happens once the anno has been removed and is a sigh to Stop :daumenhoch:

Post by: animal on April 04, 2014, 09:08 PM: The lettering has stayed as its paint . This has also stopped the ammo being stripped underneath . Unfortunately when ally is stripped it takes shit loads of work 2 get a nice finish again . I just done an Ultra Dyno resto the same. Pics in this board bit lower down ;)
