Colour Matching Butyrate Dope

Post by mike newall » Tue Feb 26, 2008 3:55 pm

We are recovering the tail surfaces of a Tiger Moth and need to match the original yellow dope. I have tried Skycraft, they don't have a close match. Does anyone know of a matching service like auto paint ? We are using butyrate as topcoat to match the previous finish and for ongoing ease of maintenance.
The only reference we have is a note saying it was 'Golden Yellow'. It ws painted by Lincs Aerial Sprayers in 1983.

Butyrate dope colour

Try LAS, they advertise mixing colours. "Golden Yellow" is a standard colour ( BS381C 356 I think), being the shade in which my piper J5 is finished.

I think you will find LAS can only produce colours to standard Randolph colour card formulas. If you need to colour match I think Randolph in USA will do it, come up with the mix formula which they can then pass onto LAS (or any other distributor of their paints).
Of course, this all take a while to sort out.....
I had a similar problem when I had my wings recovered. New "Lockhaven Yellow" is a few shades lighter than the rest of my "old" paint.

I had a problem getting the right shade of white after Randalf changed hands and LAS managed to mix some up of the right colour and even sent a small amount of tint with the new dope so that I could adjust it further if needed. They are definately worth a try.

Mike,

I have a number of different tins of Yellow Randolph if you want them. Got them with my Great Lakes, the guy was obviously trying to match the yellow!!!

Think you know how to contact me :D
