Sadly, for me, I have the one VF-1J to commit, and Carpal Tunnel to boot, so I won't be the one to try.
I had been in contact with the guy who did that fab DX VF-1S Jetfire custom to hire him to do that 1J reissue up as AXOID, and he was the one to state the joints (some of which are exposed) won't take paint, and will basically ruin the appearance. That is, unless dye was used for those parts, and he had yet to ever try that on a custom. So, here I am.
