Repaint over a pink bike My son is now 6 years old and has outgrown his small bike. There is a bike available from his elder sister but it is pink colour. This pink bike might work for him for a year or two before he outgrows it, but he might want an other colour.

I am wondering if there is a simple way for me to paint it over with a red or black colour without removing the existing paint ? I would like to keep it on the cheap side, around 10 or 20$.
Use this as an opportunity to teach him how to paint. Yes, you'll do much of the work, but you two can work together to pre-sand the existing paint, mask the parts you're not painting, and spray the new paint on.
