I will continue to go on record as being against powdercoat for a lugged frame. Sharp edges are areas where the powder will always taper out in the baking process. Multi stage PC jobs do help, immediate spraying after media blasting can and does help. It is cheap, you get what you pay for.
on a 753 frame... if you wish to kill its value, go forward.

Strong opinion? Yes. I have four bikes that when if bought them were powder coated, really ugly rust worms upon chemical removal.
