Gary, glad you figured it out, but, all you had to do was ask
Tak green has been available for MANY MANY years, over the counter. Toyota "Gypsum" is SO darned close, you may as well call it a match. Holts used to make it in touch up aerosols, but it has been discontinued in their new line.
SO, I went to my mate at Aussie Auto who is a master spray painter, and had him mix up several 300g aerosol cans (cost is $25 each - I can sell these to whoever needs them) - and I had him make as-new, as well as "old UV faded" versions - we checked with my new Tak and my OLD Tak to ascertain if correct or not.
The paint code is DST17 GYPSUM, and there are 3 variations. You need the one with more WHITE in it, as the others have a little more ochre or green. As mixed, it comes out gloss, but matting agent can be added to the can. An alternative is to spray it with satin clear after it dries.
If you want the Tak "casting roughness", just hit the primer coat with a tiny overspray of any hammertone - just a mist, not enough to even cover, just to "inflict" a few lumps here and there to it. Then re-prime, and then colour coat it.
I supplied Col "Flashdrive" with a can a couple days ago, and a can of satin clear.
The white is "Corvette White" - again, there are a few variants, so I am having one of each made and then trial them. The white changed over the years too and is now more cream to the older almost pure white.
Then there is the Tak Neutral Grey (OLD colour they used on the castings) and the Epsilon yellow. I haven't bothered as yet with those, as I don't have a sample of either.
Regarding spectro, it WON'T work if you have a curved surface - if they took the sample from the finder base flat area, the result may have been more accurate. If from a curved surface, the white balance is off, as are the blacks.
