I use automotive paints. Primer undercoat and then a semi gloss black.

Your prep work is just as important as the paint. The cabinet must be smooth with no scratches, dints or even pin holes. These defects will be seen under the new decals. Grab some tack rags as well.

Bunnings paint - I would not use them but White Knight are very good quality, but you will need primer / undercoat.

Don't use flat acrylics.. its a semi porous finish and the decals wont stick as well as a dead smooth finish... the more gloss the better adhesion. Make sure that the paint has fully cured also.. if its still degassing when you put the decals on then they will lift as the fumes/gas gets trapped underneath... it leads to ripples etc later down the track
