Shep Paine said if you can see it you can paint it. If it works for him…
I all boils down to attention to detail I guess. I’ve seen instances where someone adds painted tools after painting the tank, and you can see shiny areas of CA where they glued them on. Others paint them afterward, as I do when I can, and you can see minute bits of sloppiness where paint gets on something it shouldn’t. I try to avoid this by using pieces of Post It notes underneath tools. Whichever method people use, if they would just go over it with an Opti-Visor before calling it done, they could catch a lot of those small mistakes with CA or paint.
