Throttle bodies

[bob joyce]

i have not done ceracote yet, but i looked into it and all you need is a little dash gun and shoot it like any other "paint'
it is actually easier to get the desired finish.
google it and visit their web site
they will send you sample cards.
you sand blast the object with 100# sand for the preparation

Thanks Bob.

Can you expand on the Dow treatment? Is that something the home mechanic can obtain and use? I have mine all apart and ready to go together and they would look really nice with a new finish.
Thanks,
Jule

The proper Dow application formula for long term protection and depth of black color involves certain chemicals I will not mention and involves a boiling @130F for about 20-30mins.
But you can use a simpler Dow formulation #19 which is available from certain stores or you can mix it yourself if you can buy the chemicals. Its not as powerful but gets the job done. Clean grease free parts are a must. Wear latex/rubber gloves too not leave your finger prints. Mix 1.3 oz of chromic acid with 1oz of calcium sulphate too 1 gallon of water. Mix it well for 15 mins. Dip the mag min of 2-4 min. You don't need to clean rinse, just let it air dry.

I'm aquiring MFI from TRE. I will be selling my 2.4E parts soon. Here is a picture of the throttle bodies. The other parts should show up this week.

Hi Chris - wondering how these reproductions are working out. The Eurometrix site has a section on fixing reproduction throttle bodies and states they have seen issues. The cost to fix is not cheap. I am hoping to go your route.

For those wanting to experiment, I would not as this is very nasty stuff, dow published a book in the 50's detailling the chemicals involved and the process steps. I found mine on e-bay

I don't have an answer yet. The engine build is just starting.
