I'm trying to dap some old lithographed tins. Unforutnately, the
image on the tin keeps flaking off. I tried lining my metal dapping
block with suede and coating the tin with a couple coats of Krylon
acrylic clear coat. I also tried several different tins. No luck.
Does anyone have any suggestion on how to preserve the images on
the tin and still achieve a dome?
I don't think that you can. You are stretching the metal when you
dome it and the paint can not stretch at the same rate.
