taping base

I am laying out my next parts for painting. My plan is to hang the hood and engine deck from a ridgepole so that I can spray both sides with base and clear in a single session. When I hung it up the center of gravity on my beetle hood means Id be painting the outside partially vertical but mostly overhanging. I just know this is going to lead to issues for me on the clearcoat. My thought was maybe I can do this on a paint stand in the coating windows if I do this.

  • lay out epoxy on one side, wait overnight and do the backside. Then sand.
  • Hang and shoot base to both sides since this is shot lighter and less chance of sags, runs, and wave.
  • wait ? hours from last coat, 3 planned
  • tape and plastic on the outside of the hood with tape stick only on the inner hood lip.
  • lay hood upside down on paint stand
  • shoot 2 coats of clear on the inside
  • wait an hour or two and remove tape and plastic
  • either leave in this position until the morning or shift into the hanging position so that the base continues to offgass overnight without being in contact with the paint stand
  • In the morning tape/plastic off the inside
  • lay the hood back on the stand to paint the top along with all the other parts that sat overnight
Base is Motobase LV. I'm just unsure if having tape on base for freshly shot base for a few hours is an issue, and if not how long to wait before taping.

I'm guessing you are hanging it from the hinge end of the panel, what if you turned it 90° and hung it from the hinge and latch ends.
Just thinking out loud here.

i was actually hanging from the nose, I am going to try some other positions today to see if I can improve it, but basically the curve of the hood places the center of gravity such that one section is going to be overhung.
 
Can you double hang it? I mean suspend it from one end, then also suspend from the other end just enough to minimize or eliminate the overhung section? Haven't seen a VW hood up close in decades, so take my suggestion for whatever it may be worth.
 
If you are going to do it in two stages, do it like this. Get the entire panel in epoxy. Do the underside first. When finished let it sit in the sun for 6-8 hours minimum. Come back the next day and mask off the underside. Lay 1 1/2 or 2" tape along the inside edge leaving a portion of the tape off the panel. Then connect all the tape with paper not plastic. Scuff any overspray on the topside. Wipe down and proceed. Get the mask/tape off as soon as you finish.

If you hang it, you should hang it from the backside so to minimize the curve. I can't see why hanging it wouldn't work.
 
I was hanging it from the inner nose. I got some help over to flip it and hang from the inner side closest to the windsheild and the balance is better that way. I think by adding a wire through the handle bolt hole I can pull it toward the booth edge and get a more managable position for doing this allover without taping.

Why paper and not masking plastic?

Because it doesn't breathe plastic can etch the paint on something really fresh. Solvents come up from the paint, can't escape and soften the clear/topcoat and then the plastic mars it. Using paper is much safer. I would only use plastic to mask something that has had time to set up for some time. Something fresh never. Paper will let it breath so chance of marring is lessened. You never want to let anything be on fresh paint any longer than neccesary though.
