Jim, as always, thanks for you well considered advice.
I've always tried to keep things as uncomplicated for myself as possible, using the most readily available products. I have said that when confronted with a problem I first look around my shop (upon whose shores stuff has been washing up for years) to see if I can solve the problem with what I have at hand. Usually so. Not often the most sophisticated solutions, but satisfactorily doable.
I never took up spray brushing. There wasn't any need for it restoring furniture that I couldn't do with a brush.
Much more challenging with models. Especially J-class boat hulls. I did use commercially available spray paint on "Endeavour I" and "Rainbow" which worked out ok.
I painted the hull of my Shamrock V with acrylics and a brush, with the result, according to the critical eyes of some honest model building friends, that the outcome was successful. But not without a LOT of anxiety and sweat equity. One heck of a lot of sanding with fine, up to 6000 grit paper, which you can't use wet on acrylics, I discovered, much to my chagrin. No matter what, if you use brushes, there will always be a ghost of the brush strokes. Whether in reality, or just in my fevered brain, I ain't too sure...
