can guns be anodized OVER a old ano job

[bornl33t]

Well I got to thinking... suppose I had a solid color gun and wanted to make it a fade... can you anodize OVER an existing anodize? why not?If not then how do you get 2 colors on a gun? If not how do you fade anodize a gun ? What about a splash?

I guess what I'm asking is from someone to help me understand the process...never done it, never seen it done... wanna know how it works.

No, it must be stripped back to the aluminum.For the rest of the info,search,there is tons of info on it.

If I remember Vangogo had a thread running the whole thing step by step.

If you re-anno on top of an pre-existing coat it most likely will chip or not last as long as a stripped down new anno.

Not even close.

You must strip the anno so the part is conductive again, so it can accept a new layer of anno. It's not like a layer of paint. It's laid down in an electricial chemicial reaction. There are plenty of threads and/or sites that describe the process.

joey d, that process is used on cookware and other things, not commonly on paintball parts.

This is the method used on paintball parts:

buh.

im pretty sure vikings use type 3 anno.

heres another from warpig:

From what I understand Hard Anodizing leaves a grey color that's harder to dye, and would be imparted with the grey behind any color. So bright colors are not really possible. But I have never hard annoed a part before. I have sulf annoed parts and dyed them, they turned out ok, not at nice as I hoped, but I have only tried it a couple times. Still getting everything setup.

to get back to his question.

the reason you can't go back over the top is that it has been sealed.

when you anaodize the first step is the anaodizing step. this puts a layer of what if you looked at under a microscope would look like little tubes.

the second step is to color.

the third step is to seal.

this is a basic layout of what happens so dont come back and flame me with.. but you still need to do this... blah

so as you can see heat if you have sealed it you cant dye it anymore.

as to how do you do fades. you anao it, then hang the part in the first color to the point of the fade, when it has enuff color you turn it around and hang it in the second color.

as i said this is a basic example to help heat under stand what goes on. there is MUCH more to it then this

I"m sure you meant can't,just to clear up any questions.

there are a few problems

#1 the parts you wish to annodize must be electrified, and once the part is annodized it becomes non conductive in order to re anno it it would have to be stripped to become conductive again.

#2 the parts need to be super clean , the way most shops clean the parts are with etching chehmicals, that will stip the old anodize anyway.
