Paint assembled or not

[SRC]

I would love to hear from some experienced shops and painters on their paint process. One common debate in our shop is the decision to cut in then assemble to final paint....or paint while completely apart.

Of course there are many considerations with regard to color choice, metallics, pearls etc.
So disassembled paint is not always even possible.



I've seen many SEMA build posts here and I have see the progress photos done both ways.
With the many products available to correctly tape off jambs I would like to see what others are using. Currently I'm using the 3M 3 step tape that peels in layers from sealer, to base then clear.

Your comments and advice are appreciated.

Thank you
