Ive done this to my black clio too! what colour are you going?
Basically the front one just pulls out. The rear is a little bit more difficult, you need to take the plastic bit off the inside of the rear tail gate off so there is 1 screw on the right hand side as your looking into the boot, undo this and then the rest of the plastic bit just pulls off! Did mine a while ago and from what i can remember, there are 3 10mm bolts that you need to undo and then basically the whole handle can be removed from the outside! I actually snapped one of the wee clips on the rear diamond because i was trying to get it off the handle but it turns out that it was glued on from the inside, if yours is glued on too you might need to just masking tape around the diamond before spraying!
With regards to actually painting, I gave mine a really good sanding down with 800, 1000 and 1200 grade sand paper, then 3 coats of grey primer, 3 coats of gloss black paint, then 2 coats of laquer and they turned out really good. Really happy with them!
Not sure about how to do the bullets though? Maybe they just pop off, i havent tried though!
Hope that sents you on your way mate
