Has anyone put a clear coat on their GTS wheels?

Apologies if this has been covered elsewhere but I'm getting my rims painted at present in the later gts rim paint codes as they're for a HZ. Old mate painting them said the paint codes are for Dulon acrylic which is fine, but he asked me if I want 2k clear over the top to give a more glossy finish. My question is whether Gmh put clear on? I don't think I will bother with it but interested in what others reckon? TIA
