If you are using acrylic sheets which are in correct color then you dont have problems with paint not sticking which was my biggest downfall with 1mm thick aluminum plates that I painted, and glued and just few weeks of driving paint started to come off. Plates are still there as you migth have seen from other videos.
How they should look when finished.
