Hey all members, i am really enthuisastic on mtb, but my bike is pretty old GT mtbike, but works 100 percent. I want to paint it 100 percent black. What kind of paint should I use, can I just use spray paint from hardware store? Would it rust and break down on rain water?

Thank you for all answers

Steel bike ? for a fully stripped frame, primer coat first then rattle can, flat black would be best.

Aluminum,, no primer needed.

Both need some sanding, rough up the paint for stick,, gloss black harder to make work,

Strip to the frame, 800 grit, the whole bike, rattle can it. Light coat/spray, let it dry, repeat, repeat, thin light coats, many
Never point the can at the frame and then press the button. press then sweep across the frame.
If spray is coming out of the can your hand must be In motion, sweeping, say 8 to 10 Inches away at all times.
You sweep left then right over the frame, right where you changed direction the paint will pile up..
sweep away from the frame each time....

After a coat turn the rattle can upside down and press till it goes clear, this cleans the nozzle.. don't do this and you may be re sanding a blob.

Always wanted to do this but I nervous about having to breakdown and reassemble the bike...

Also, taking apart the lower crankset seems like it would be a total pain in the behind! Maybe I will do this after the riding season so I will not miss out on too many weeks of riding....

Get it powder coated, may cost more, but will get stripped to bare metal before, so no rust left, and be durable in the long run, rattle can home jobs won't last any significant length of time before wearing through.

Also, what is a 'lower crankset'? thinking you may mean Bottom Bracket, if re-finishing any frame, you would need to strip all the parts off, headset, BB etc
