Sheesh, another A-RT run sold quickly again.
The big question I have is did anyone even receive a new grail WITHOUT any flaws? Everybody chiming in has gotten some kind of issue that makes it non-mint and even verging into B-grade territory.

When I got my orange grail I never noticed any ano flaws that were obvious. But I didnt know I was supposed to look so its not like I inspected the whole thingâŚ
Nope. Electro-plating would require a ton of different metals to achieve that kind of colour and it wouldnât result in a rim that would change colour depending on the light shining on it. Iâll say itâs impossible to achieve such a colour with electro-plating. The rims are torched but Iâm not sure what exactly causes the marks. I know they can be avoided as other companies like G2 and Mowl have perfect rainbow rims.

My machinist said thatâs where the rings are held while they are being torched (at least for my yoyo that was affected by this, the Exia). Because heat can transfer through that point to the mounting hardware it results in different color bands appearing. I think some shops (FPM, etc) have more sophisticated mounting setups that can place those spots anywhere, which allows them to be hidden where the ring touches the aluminum body.
It inspired me to make another outer-ring model at least.

Not really. They can do rainbow on stainless and have for many years.
" Prismatic Stainless Steel (color produced by electrochemical process that creates thin layer of chrome oxide)."
Or -
SS colour anodizing(only for 18/8 SS):
1 lit sulphuric acid
7,5 gm sodium bichromate
object=anode,cathode= lead
70-95 °C temp.,0,06 A/dm2, 1,3 V
Colour sequence brown - blue - yellow - reddish brown - purple - green.
Interesting, did not know about this. But I think most of the rainbow rims out there are done by torching. Maybe some manufacturers can weigh in on this @G2_Jake @Mazdarx7FD @bjardin @yyfben2.deactivated

I know in jewelry, watches, pens etc. electro-chem is common. Same as it was decades ago in the motorcycle accessory market. Had a blue fade on a steel can exhaust that was done this way and looked great. Headers turned colors on their own from heat. 
I do wonder if they can do a clear coat like aluminum as some seem to have something like that while others donât and the torched style are usually the ones that donât.
TWSBI Vac700R Iris with steel nib and accents.
Always meant to do some nickel plating from Caswellâs on a yoyo. I remember when OD did the Obsidian plating but I think it had potential health issues? Iâve done several Ti pieces which was fun but the oxide layer isnât durable really. Still fun and high voltage!
Hopefully some of the people you tagged will respond!

Ah interesting. I think iYoYo might use this finish as their finish is similar to the picture shown. Itâs less rainbowy and has a majority of one colour, either pink or green.
I reached out to A-RT and theyâre asking that people that have flaws on the bright brown B7 Grails reach out to them at alternate.rt@gmail.com
Make sure to include a photo. Sounds like there will be a refund issued
Tagging @yoyojoe I know you were one of the ones that received an imperfect one.

Maybe itâs this? PVD coating, Physical Vapor Deposition.

Yea it might be. It seems to be the same colour at certain regions, which is similar to iYoYoâs rainbow rims.
