I guess Trek frames have well defined lugs, but I have a triple butted Ishiwata generic "Saint Tropez" late 80's branded bike that is all scratched up and is painted a lovely "Duran-Duran" garish faded milky red (think pink) to pearlescent white fade. Its a really solid bike and its comfortable and fits me well. But...its a perfect candidate for a powder coat job. The bottom bracket lugs in particular have hollows inside of them, a very ugly, dirt sucking lack of attention to detail. I guess that the thick powder coating might flow into the offending area, acting as a filler. But a good frame painter like Joe Bell, who charges $400 on up by they way, could do all the little things like removing and re-installing headbadges, re-glueing stainless chainstay protectors, or , in my case, filing more pleasing transitions onto my poorly executed (but perfectly serviceable) lugwork.
