Is there anybody ever hand-prime the model kits? I tried to find in several forums, everybody using spray or airbrush for priming.
I tried last weekend, I was using Mr. base white 1000. I thinned it with 60:40 ratio. But the prime seems too runny, it also look it does not stick very well.
So I wanted to try to hand-paint it without thinning it. Will it work? Anybody can share advise on this?
I think lacquers are hard to hand-paint in any case. Lacquers dry quickly, of course, but they also have the rather unique property that dried lacquer can absorb lacquer thinner and become liquid paint again. It's not like working with enamels or acrylics, where you can paint over the previous coatings (once fully dried) and trust them to remain solid. If you paint wet lacquer over dry lacquer, the dry lacquer is going to become tacky again, and that makes painting on top of it difficult...
Otherwise, if you really want to hand-paint Mr. Base White, stick with the thinned stuff. Spread a thin coating of it - and on successive coats, apply the brush to any given area just once, when you initially add the wet paint there. (Gliding the brush across that area again before the newly-applied paint can dry fully would quite possibly cause the brush to stick to the under-layer and tear the paint off down to the bare plastic in that spot...
It might be doable - I haven't done that much hand-painting with lacquers and when I have it was usually just detail work. But if I really, absolutely had to hand-brush primer, I'd use enamel. It's not as strong as lacquer (or so I've heard) and it takes longer to dry - but its properties are better-suited for hand-brushing. Specifically, if you paint on a layer and it fully dries, painting on a second layer shouldn't affect the first. Slow drying time is good for hand-brushing as well.
