How to repaint plastics?

Did anyone had experience with plastics repainting? I have three plastic parts that are painted only with basic colour. I would like to prepare plastic parts so they are veeery smooth and after that paint them in custom colours. I was given the advice that I should use plastic primer before painting and paint at least two hands of colour. Advices, perhaps links how to?

And sorry if my english is not so good, but I hope you understand my point.

Im terrible at painting, all my paint jobs peel off. But good luck! Make sure you sand down the original coat before you apply primer. I think thats where I go wrong.

I'll take care on that, thanks for advice.

Painting plastic parts is the same as metal,but you use a different primer and the paint usually contains a plasticizer.:thumbup:

Thanks, this is what I've been looking for. Very detailled and systematic.

I tried painting my bike recently.
I've got to tell you, it's a hell of a job and the results may be not as expected.
One thing is for sure: Get a decent clear coat lack, or you will regret it (as I did)

1st thing is to get a rough even surface by sanding it down with different sandpapers.
2nd apply primer 1 - 2 coats
3rd paint evenly with 2 - 3 coats.
4th apply clear coat.
