I'm rather enjoying this lining lark. This is the progress on the Coffee Pot, using a Bob Moore lining pen.
The black base coat is in cellulose, and the lining is in enamel. This has proved to be a superb combination. It's possible to allow the lining to harden slightly, then tidy it up with a very fine brush loaded with turps.
I'm sure that it was in the book by Ian Rathbone that I read this first, but it does make life very easy.
I'll look at the model again in the morning with a fresh set of eyes to see if there is anything else that needs correcting. And maybe add in the brass of the window surrounds, to set off the red lining.
