Yeah the mould height is important to fix I think. It lets the user cut more freely when it comes to trimming. I only have a little bit of height in the armor pulls, so if I trim too much, there won't be any height left! So I think it would be good to add more of it, know what I mean?
Nonetheless, the armor looks insane! I love it. I'm scared of putting dents in myself, cuz I'm afraid I'll break it 
How should I do it? Heatgun?
