"RE-COLORING CARBURETOR BODIES"



2000

Q. I need to find a fool-proof way to correctly 're-color' old carburetor bodies to their original "iridescent yellow / gold rainbow" coloring. These bodies are made of a zinc die-cast alloy ('ZAMAK 3 & 5'). Does anyone know the correct procedure for doing this re-coloring ? I appreciate your help! Thank you!

A. Hi Larry. I am told that the best way is by zinc plating the carburetor bodies first. To me "fool-proof" probably dictates "best way" not "a possible way". Good luck.

A. Regarding recolouring carburetor bodies, particularly zinc die-cast types such as Holleys, Zinctone from Turco is a professional product used in Australia. Available from Avanti in 20L drums. In USA check with Turco division of Henkel Technologies.

Q. I need information on the process for recoloring classic car carburetors to the original yellow dichromate color. I believe it is a hot dipping process.

Q. I have occasion to refinish several small pistol frames made of cast Zamak. The original black has worn from the edges and high spots, exposing the cast material which is now dull gray in color.
What should I do to prep the surface?
Then, what specific formula should I use to achieve a finish color similar in tone to this:

Any after-treatment or sealer or stabilize?

A. Zamak is zinc based alloy so you can use any zinc colouring method. Try next download free booklet on metal colouring and plating:

- there you can find some zinc colouring methods.
Hope it helps and good luck!
