My guess would be to use ScotchBrite or 1000-2000 grit sandpaper to clean up surface then degrease with isopropyl alcohol then use a high temp paint like engine block paint.

Or just get one of these. Cheaper than the paint.

If you do not mind, what is the procedure anodized ?, which materials are used ?, his work is admirable.

I get my materials from here
http://gaterosplating.co.uk/Anodising-Kit.php
It is easy to simplify the process but these are probably the best videos to watch
There are many different variables and it takes practice. Don't try this on a valuable or difficult to replace model engine part until you are well practiced.

Re: retrieve the color of my Black Widow¿?
Kari friend, I think it's a subtle solution !.
I would like to restore the black color, but I think I should find a solution that is not very expensive as it is in one piece. I wondered if an epoxy paint could somehow improve the appearance and endurance while fuel ... ???

Ian, thank you very much for the information really is what should be done, but because it is one piece mmmmm I see you opt for an alternative solution not mean it is the best, but maybe I was glad a little see the appearance of the engine, the better!

Re: retrieve the color of my Black Widow¿?
Sadly this is the fate of every used black widow. The cheapest and easiet route is to replace the case. Even cheaper would be to use it until it can't be used anymore.

Re: retrieve the color of my Black Widow¿?
Adonising is a hobby in itself. There is quite a learning curve but once you have the setup - it can be very rewarding.
For "one off" restorations - it is not worth the trouble and the expense.
But - once the art is mastered .......
Take the grottiest looking crankcase - this one was originally black but unloved and corrosion had set in ......
I combined this with tidying up a DC Bambi cylinder head and a few other parts (can't remember what they were!).
I chose not to use black dye as this was a used engine and after restoration - it would look new and unused.
The Bambi was unrun but the head had been scratched in storage.
Oh yes - now I remember - one of the other engines was an ED 2.46
It is difficult to match parts - same dye, different aluminium - results in a different shade - all down to timing.

Re: retrieve the color of my Black Widow¿?
Mauricio, I finally cleaned up the Black Widow I showed earlier and also added a starter spring. This kind of spring does not cover the damaged area completely but I think it looks OK. Not new or perfect, but but not bad either. It looks like an engine that has been around the circle a few times and I like it the way it is

Mark, do you still do this? I have one of my Shuriken's that had a head on with another engine, it also has it's anodizing ground off to achieve contact with the battery clip. Ken

Re: retrieve the color of my Black Widow¿?
I might dig it out and do some this winter, if so i'll let you know, if it's gold i don't have dye. Also, if the case is machined or extruded we're good, cast aluminum doesn't anodize very well.
