Just to complicate things further I noticed in one of the Austin factory films of the 1930s that the wings were described as being "dipped in black enamel". Difficult to imagine how they got a good finish.
The term "enamel" seems to have been used for cellulose, spirit based and synthetic paints at various times. I had a couple of tins of cellulose enamel in the cupboard until recently.
There is a good chance that "dipped in black enamel" meant stove enamelled. i. e. dipped and then heated in an oven at 120c.
I believe that in the "paint process" multiple coats could be applied - though I doubt that. in a production process, they would have been rubbed down between. I understand that early cars (1923-24) had stove-enamelled wings as did the Ruby - but that might not be true, unless we can unearth some solid evidence. Stove enamelling is still carried out - https://goldburnfinishers.co.uk/stove-en...SwQAvD_BwE and https://blastreat.co.uk/stove-enamel/ and https://www.keeppowdercoating.co.uk/stov...index.html There is also 'Vitreous Enamel', a rather different process: http://www.trico-ve.co.uk/contract-enamelling/
