Stripping / Painting / Coating / Cleaning Rims

If i want to paint a seat post that is anodised, do i need to remove the anodising or just paint over the top with primer, i assume there is no need to remove the anodising but just want to check

PS - avoid the jokes of needing multiple cans to paint my seatpost

You will need multiple cans of spray paint to paint your seat post, in fact it might be like the forth bridge which is so long that as one team finish painting at one end a second team have already started to re-paint the other end as it take them so long.

Anodized surfaces are very hard and flat, you will need to key the surface a little so as to allow the paint to mechanically stick to the surface. Otherwise the paint will flake very easily.
