I got mine from ebay, but you could go to your local automotive store ( AutoTeileUnger e.g. here in Germany) and let them mix RAL 7034 if they don´t have it ready. Probably not the cheapest way. I paid for 400 ml on ebay about 9,50€.
And with the red primer...... I was simply to stingy to buy a can of red color for only one microgramm that I need.
So I will just hit the inside with a little bit of white color, but the red dust will be missing.
Both was present at the originals, so that will not be the apocalypse
