Does anyone have a colour match for the light green colour that AMAL used to paint some TT carburettor bodies and floats?

And can anyone tell me why they painted some and not others?

Over the years I have seen a couple of restored bikes with 'painted' carb bodies. Always found it hard to believe the factory did this....

Years later when I purchased my gs the carb had a greenish-goldish look and it does not look like paint. More like a -Chromate Conversion- common to many alloy carb bodies on some 60's cars.

The best I could come up with is a product/process called ALODINE. Do a google and you can find more interesting info on this.

I would like to give it a try, but have not spent any time sourcing. Sure 'seems' better than paint, and looks like what my gp alloy has been treated with....

Perhaps other can comment...

cheers

AMAL brochures for their aluminium bodied 'racing' carburetters describe the finish on the mixing body and float chamber body as "sprayed on durable and attractive metallic lacquer"
ALODINE is a chemical coating used on aluminium to promote the adhesion of primer and top coat paint layers. It is relatively 'soft' and non abrasion resistant but used because the process is cheaper than the alternative anodizing. B.M.L.S.

Thanks for all responses so far!

I have a NOS TT body that still has the finish on it. The colour is a bit faded but is definitely painted on rather than a chemical treatment.

It also doesn't stain or dissolve when soaked with petrol.

That makes sense but limits my choice when I try to find a match.

I recall the GPs on the Spitfires Mk-somethings, the ones everyone threw away, as being distinctly light green. The earlier ones I've had, including a GP that was taken off a DBD a week after it was delivered in 1963, are the very thin gold, so think it is more like a wash or a stain than paint. Though heavier and more coloured than alodine.

Resurrecting an old thread. Anyone out there have any info on this subject?

bels posted above about AMAL brochures mentioning sprayed on lacquer. Anyone out there have a brochure that does mention it? I’ve search around and read a few, but no mention of paint.

I have two TTs and a GP, but all three have silver bodies. Which is a shame, since there's a 50/50 chance I could identify the pigment with my Raman spectrometer. It's hard to tell the true color from the photographs but it easily could be cadmium plating

I’ve been collecting photos and it seems as though there were different shades... different colour even. Plus whatever it is seems to fade and “reasonably” sure it’s not plating. Not sure where the OP got the green from, although I suppose you could argue the first one is sort of green.

MM, do you have any AMAL brochures? Wonder if bels‘s post is accurate. I haven’t seen any that mention paint, but haven’t seen many brochures.

I found six different ones for the GP and GP.2 and two for the TT, but a very quick flip through them didn't show any mention of finish. I'll have more time to look 90 min. from now (but by then might have forgotten ...).

No rush... won’t be painting anytime soon. We became world champions today. Even stopped going into the shop, because it’s not that airtight.

I always thought the coating was a varnish type that was sprayed or brushed on. I've seen some carb bodies that even had runs in the coating.

Well a run would certainly confirm some sort of paint or varnish.... and that is GP I assume,

I spoke to a friend in Portland yesterday. Yikes!
You can tell it’s not just forests burning, smells like tires, plastics etc. ..Hope you are somewhere safe.

I'll see your 270 and raise you 61. This was the reading in Melbourne when we were visiting potential lenders there in January.

However, we only had to breathe that toxic air for a day, while you people on the west coast have been living it for a lot longer than that.


p.s. I only read the two TT brochures, because that's what you asked about, and neither mentions cosmetics, like possible paint or plating.

Yes, inside my house. One side benefit might be that a lot more people are staying inside and self quarantining.

And yes, a NOS GP 1 take off from a G80CS.

As the owner of the 10TT9 pictured below, I can vouch for the accuracy of the color rendition:


[Linked Image from live.staticflickr.com]BDE35D6F-5288-49DF-BD70-A4037610C871 by First Last, on Flickr

Further, having owned that carb for the past 38 years, I can say that the only thing that's happened to the color is that its intensity may have faded slightly.

BTW, for anyone who may be interested, I have that 10TT9 up for sale currently, along with a GP1.

Some AMAL Monoblocs sold new in the "aftermarket" in the 1950s also were that color.

The dual carb manifold and Monobloc kit for the Triumph T110 listed in the TRI-COR catalog for 1958 shows a full-float bowl and a chopped Monobloc.

I have both, and they have traces of this color on them. The color is a gold that is close to that which some Chrysler engine block were painted in the 1950s.

Was this supposed to be a protective coating, or just to simulate the old bronze Amals?

Gregg,

Any idea what the coating might be?

Eastwood sell various carb paints/lacquers including a bronze translucent acrylic enamel which might work, see This Link

This is meant to replicate the original zinc chromate plating but whether thats what AMAL used is anyones guess.

Well if they ever reopen the border and shipping gets back to normal, I’ll buy some and give it a try.

I never gave the subject much thought in the past and just assumed what colour was left was just varnish/ residue from fuel. I just went through the bin and came across these. The one on the left shows the coating was washed away by the fuel coming out of the vent hole. If fuel removes it over time, then likely any carb cleaner would rip it all off.

Just checked the US Eastwood site and can’t find it listed. Searched with the description and then with SKU.
Sent them an email... will post the reply.

A friend use to work for a company that supplied parts to aerospace industry and home-built aircraft market. They applied alodine to some aluminum parts. The process they used involved dipping the part into the solution. The color would vary depending on how long you left the part in the solution. I believe alodine was considered a protective coating like zinc-chromate on steel.

Spitfire GP's didn't look to be colored, so I went with the natural original finish.
