Title: De-annodising and Polishing problems.
Post by: southern andy on May 07, 2009, 09:54 PM: Help :LolLolLolLol:

Ok, scenario....... I got hold of a couple of sets of Araya 7X rims. One pair were pretty good but the other pair, well, one of them needs a lot of attention.

So i stripped one rim of its gold anno yesterday with oven pride then a few mins later when the gold had gone i went and rinsed it in a bath of water making sure it was rinsed thoroughly. It turned a whitish colour which obviously required polishing. I ran out of time so slung it on the side. Today i progressed with the other rim, again same way but this one i gave a quick polish to straight away and it came out pretty good by my standards, a very chrome looking Ali rim. I then proceeded to pick up the other rim and polish away only for this one to have lots of blemishes on it. :'( :'( Despite the rim being really smooth it seems marked.

What have i done ??????? I did rinse properly, should i of polished straight away yesterday ???????????

Good rim with a few bits of polish on it, no marks at all. This one was polished straight away after de-annodising and rinsing.

The blemished rim that was left unpolished for 24hrs. Its the darker marks that are the problem, the lighter marks are the good bits.

I do have a spare rim if i have knackered it by leaving it over night without polish, the thing that is confusing me though is i did rinse it, if i hadn't of rinsed the oven pride off then fair enough.

So forgive me if i'm being a little thick here :angel:

Are you saying that the rim has not de-anodised properly ????

In slightly better light today. Obviously they require better polishing but i did these by hand rather than any sort of polishing tool.

Post by: Glynnyboy on May 08, 2009, 03:49 PM: I would say what neil has for the future but all the anno hasn't gone yet. Trying to polish it off you can end up peeing in the wind as anno is meant to last. They would be back in the bag under a watchfull eye. Rub through the bag in the spots you have missed. It will come good.
The same happened to me with some araya aero's and they worked out fine. :daumenhoch:

Or take them outside, put some decent rubber gloves on and apply the oven pride direct to the areas that need more attention, rubbing in with the gloves - I use the gloves method rather than the bag - feel like i'm in more control that way :)

Post by: southern andy on May 08, 2009, 08:45 PM: Cool, cheers for all your help guys. :4_17_5:

I put another coat of Oven pride on tonight, rinsed off and gave it the finger polish with Autosol until the tube ran out.

Worked superbly, they're like chrome now and all those marks have gone. :4_17_5: :4_17_5:

I'm gonna give them another few polishes tomorrow as i need some more Autosol but i'm well chuffed with how it looks now.

Post by: Waxintaxin on May 09, 2009, 09:53 AM: Yes , good work , annodising changes the metal and whilst the dye has been removed the altered metal hasnt all gone with the oven pride

Post by: southern andy on May 09, 2009, 06:14 PM: Another polish today then and i'm well chuffed, would be intrigued to see what a polishing tool would do that my fingers cant. :LolLolLolLol:
