I'm always amazed how many time I'll buy something to do a job faster than my current tools, then find its not doing what i want and go back to plan A. I had a mile or 2 of railings to paint and rather than doing them by hand I thought "I can buy a tin of spray paint for that" (Tamiya of course, not the spraycoat). After taking everything off the model, carefully labeled so that I knew where it would go back, I got stuck in. In no time I had a looming disaster on my hands with the paint forming a string of pearls along the wire. After a quick wipe down I left everything for a day, and then painted them all by hand, as I was going to do in the first place.
Glued back on its really made the model pop (and yes, the center railings still have to be trimmed to length).
