Im kicking myself over this because the drama with the edge bleeding was avoidable, moreover I had learnt how to ensure no bleeding of colour across or under the masking line a couple of years ago, but had simply forgotten how to do it.
The best way to approach this was shown to me years ago by Terry. Basically lay your base coat down for the whole surface…say you have a blue on one side, and a white on the other. I would paint the whole model white. Then apply the masking line over the bits of white I want to retain, followed another coat of white along the seam line to seal that same and ensure no leakage across or under that seam. Then apply your second colour, in this case blue (in the example I mean) which should not cause any bleeding or seepage into the lighter colour
So I did know how to do this, but had forgotten about that lesson all those years ago. Im still kicking myself, but hopefully next time wont forget how its meant to be done
I don't know if I can do this now. The oil colour is texture based as well as colour based. I think I would need to remove the whole oil application, start again basically, to rectify the problem. If I wanted to retain the current oil application, I would need to wait about 24 more hours for that coat to harden, alternatively if I want to remove the colour, best time is now whilst its still soft/touch dry. I have managed to touch up the edges such that they are passable now I think, but the question I need to ponder is "good enough' actually good enough.....
