hey all! I bought one of the few mk3 vento's in sydney a few months ago and have only recently started to modify it (after i got my inspiration from seeing the HOT ventos during my holz in croatia and germany )

HOWEVER the black paint on the bumpers on the (front and back) are cracking and peeling, thus making the car look ****
I am now hoping to repaint them to white along with the rest of the car (as well as the side trims) how should i go about doing this? can it be done thru DIY? or should i go to a resprayer?? how much money will i be looking at here?

Thanks!
