I picked up a used bike for next to nothing and have since purchased a better all carbon bike so looking to unload the old one. The problem is it was painted with what looks like spray can paint chipping and coming off. I want to figure out how to get the cheap paint off and possible even the original paint and doing it over with original decals before selling.

Can anyone point me to a good tutorial on how to strip the old paint and if I would even need to strip the original paint or not? Also what type of paint I should use for the new one and how to get decals. I already have a paint *** so just need basic info and pointed in the right direction.
