Subject asks it basically.. I dropped a frame off today.. the place was a bit industrial for my liking, but I left it anyway.. hopefully all turns out fine..
anyway, chasing cured powdercoat out of BB threads.. no sweat if I have the tap? major PITA?
Hearing different things about masking - have to mask with foil (not tape), don't mask and chase out the threads (who has the patience and money to buy all these threaded rods?), you don't need to mask - they just blow out the powder.
An easy way is to use some old cups for the B.B. shell and appropriate sized bolts for anything else, eg : rear hanger. My powder coater doesn't blow it out with an air-***, I learnt that the hard way, but he does a very nice finish.
