Final assembly question

Hey FABO, I need input from the body and paint guys. I have my current build assembled, gapped and panel matched for final priming and blocking. I spent over 50 hours installing and adjusting everything to get it close enough. I will be shooting color in a couple weeks then be ready to assemble. I am thinking about doing something to pre-align the panels like using Eastwood's magnetic pin system. looking for input on how it worked out for some of you guys. Thanks in advance!!
