Protech dampers anodize?
Samuele - 25/3/17 at 08:57 PM

I would like to anodize my protech dampers.
some of you can tell me if you can?
mean I am internally coated or treated so that it is not possible to anodize?
I have only aluminum?

I'd be amazed if they are not already anodised. However, you won't be able to anodise the internal surfaces because anodising "grows" the surface, meaning clearances will change. But any good anodiser will be able to seal the unit to prevent certain areas being anodised.

Protech dampers are clear anodized as standard. I had mine done black at an extra cost of 20 quid for the set.

I do not know..
but in my opinion they are not anodized.
have not been used ever,
nevertheless have several deposits
for as I know,
come from the fact with the aluminum has not been anodized

You may be able to get them stripped, lightly etched then re-anodised. Anodising should not affect the dimensions significantly. Your local finishers shoul be able to advise you and give you a price.

Mine look like those pictured I suspect early units were not anodized just polished..

Caustic soda will strip off any old anodising. There are dimension changes but not a lot if you take care. Wash in distilled water. A bit of a swim in Nitric Acid. Wash in distilled water... and then ready for the anodising.

Very easy to do this yourself....

you could ask Protech for a price on swapping them for annodised bodies.

Dimensional changes won't affect external dims enough to care, but internally you'd be causing all kinds of hell.

You're looking at ~25 microns surface growth for a cosmetic coat, which is nothing external (.025mm) but when your piston tolerance is sized in single microns you could well end up with trouble if you don't do it properly.

Get it done properly, don't do it yourself.

Any ano coating can be damaged by impact or scratch - you could be seeing a spot where you clobbered it with a spanner or it bounced off something in the box when it was shipped.

I agree with the statement that the thickness of anodizing is very low.
and you're not wearing any serious problems.
Here I have someone doing this work anodizing.
so not worth me to do the tests.
the main question is though,
if the absorber interior is surface treated with materials not suitable for the anodization,
such as Nikasil.
if you make it all very complicated.
I'll try to ask alls protech if they know something about it
