Need advice for masking before painting
Hi all, I’m about to sell a nice Cycleops Spin Bike, and I was concerned about the cranks which were getting a bit of surface rust on them. I soaked them in rust remover, which knocked out the rust, but also some of the paint. I want to hit them with a fresh coat from a rattle can, but what is the best way to protect the threads when painting? (I will only paint the crank arm on the drive side - the ring will get masked off. TIA!

I usually just try to stuff a bit of tissue paper in to catch most of it and then clean any paint out with acetone afterwards.
You can also make a crude thread chaser by cutting a couple of longitudinal slots in a bolt the right size. That will clean out any last bits of paint.

Just roll up a small piece of paper, insert it into the hole and let it unroll to fit the hole. I do the same with head tubes and bottom brackets when I paint a frame.

A proper tap also has large slots. These are for actual metal chips, but a tap can also be used just to clean up a thread if you have one the right size.
Not sure what the sizes are of crank and pedal threads. I think the crank bolt usually needs a 14mm socket and 13mm is usually what goes with M8.
