GSX750ES Carburetor coating

[Guest]

As part of my restoration I dis-assembled my 4 carbs into the smallest parts and very thoroughly cleaned them only to realize that after 129,000 km the carbs aluminium looks bad. It has a blue grey color with black stains that look like aluminium oxidation.
Other than paint, is there any other known coating used to restore the shine of the aluminum of the carbs ?
I can achieve that with a Dremel tool + a gentle brass brush head but it will not last long before new corrosion will be visible..

get them soda blasted and coat them with ACF-50

thats ok if you want your carbs smothered in grease!

I was wondering about that. Seems that a light oil would attract dirt.

Chuck Hahn was using some aluminum product a while back, Aluminator?

Chuck?

Otherwise, soda or vapor blasting will clean them up

I soda blast but have never used a coating afterwards. Never seemed to need it.

The carb bodies are zinc, not aluminum. If you media blast them they will look nice for a good long while. Soda is not very aggressive so if the carbs are heavily corroded you may need something more aggressive like glass bead. Blasting the steel parts will remove the plating though so keep this in mind.

Corrosion block grease does not attract dirt since you need to wipe it off and that leaves a protective microscopic coating.
