These people claim to ship paint around the world and they list 633 Blue-Grey

I am just curious if you are in the UK, why you are going for RAL colours?   Surely any UK company could have worked to BS 381C 633 which is actually the correct colour?   Was the problem that you were unable to get Powder coating done to BS spec? Certainly paint itself is easy enough to source from any UK source.

It is suggested if you are going the RAL route the closest is actually RAL 7016 Anthracite Grey?

Hi Mike

I use two powder coaters locally and they both use RAL codes, the codes are printed on the boxes of powders.
Same story with the paint factors although I will say Iíve never tried asking for British Standard colours.
As to which code to use, Iíll be sticking with 5008.

Perhaps easier and cheaper if somone have a small piece  cutoff from some scrap metal with original old RAF Blue to send you. Then you could  ask a local paint shop to match that colour?
That might even give an old fainted correct look unless taken from a concealed protected part.

Great idea !! Happy to pay for any shipping costs. I found some model paint in RAF blue that I ordered but would prefer a faded piece as you have suggested.
Thanks

Thats a helluva nice truck
I have owned a number of RAF vehicles and trailers,  these all had areas of original paint,  My expereince is that rather than darkening it actually fades lighter.

The most original paint I had where on trailer bed side extensions from a 30 ton Crane trailer, that had never been used but were stored in a shed, out of sunlight, at RAF Cardington, more or less from the day the trailer arrived, new.

I have bought countless tins of paint mixed to 663 Blue-Grey.  Non have really matched the trailer extesions, existing paint (such as Fuel tank on a Matador that had never been repainted or the inside of the Ballast box on my RAF Mighty Antar) or matched colours from previous batches from that supplier or batches from other suppliers.

I think it all come down to the fact that the original BS381 33, and the subsequent BS 381 633 and then BS381C 633 colour only existed as a colour chip supplied by British standards ,  There was no formula as to how to make the colour, what base, what pigments and in what quantities the pigments were to be added.

Paint suppliers got the colour chip from British Standards then each company used their skill and experience to mix a paint they were happy to call the same colour as the chip.

Some companies got closer to the chip colour than others,  each manufacturer probably used different pigments in different quantities to achieve what they thought was the best match.  Each companies paint reacted differently to ageing, weather, sunlight, some darkening, some fading.

Pigments were dry pigments and batches of paint could vary in colour from batch to batch (from the same supplier)  because of inacurracies in weighing out the ingredients.

I think determining which shade is the correct shade is a difficult as determining which is the correct mix to get Deep Bronze Green.

We have all seen lines of DBG Land-Rovers,  each is a different colour.  I had been to Military vehicle events were no two RAF Blue-grey vehicles are the exact same colour.

I think the truth is there was variation in the original Blue-Grey paint that was first applied,  so if you you choose a colour you are happy with, then it will probably be correct for at least one of the colours appearing over the years on vehicles in the RAF or in Land-Rover production.  It won't however be the same as many of the other original paint shades.  ;)

Below Mighty Antar freshly painted,  compare with trailer sides and wheels that had never been repainted since it was built in the late fifties.....

Mark,

I am led to believe there are EPA issues importing paint which involve getting a bunch of special licenses to show it conforms to EPA regulations (and likely Ca has a few more besides).

I am in Tx but do have a front panel in my workshop which was fitted to a 1956 Ex RAF 86 (which I sold in UK) its a steel 88 panel so I swapped it out for the correct one.
Its sprayed in red oxide primer and then in RAF blue/gray so I guess was an in service replacement.
May be able to find a PPG paint place local to me who can scan it and color match for you.
Would be a short delay though as I am away working until mid June.

PM me and we can work out details.

Hi Simon
Thank you very much for the offer. I ordered some model paint that is supposedly the correct color. If it looks close I can have it scanned and produced from that . If it does not work out I will reach back out to you and see if we can figure something out. I got sent a link to a scanner that links to your phone . I ordered one from Amazon but it didnít arrive yet. If it looks like it works I could order one for you and then have you scan it. Appreciate it !!

Been there though not in that league 10 tons was as heavy as I got. Big trucks are  great until something goes wrong and your treasured green machine turns into 10 tons of dead metal at the roadside
Thats when it helps to have friends with something suitable to tow you back
