Amount of epoxy sealer needed?

Well cornet, I did a panel at a time and kept some records, this is my first overall but i used the epoxy only (blocking each two coat session a couple days apart) from bare metal(no 2k) for surfacing . I'm learning I have heavy gun fingers and have abused the epoxy (guess I'm glad it's spi), so my records from the past several months, are not all that accurate.
From the SPI tech manual:
To use as a Paint Sealer:
To use the epoxy as a paint sealer, reduce it 5-50% with the proper temperature range
urethane reducer (this is very important) and spray with your base/clear gun. Spray one
wet coat ONLY, let it sit 2 hours then apply paint. For sealing of a potential problem
paint job, apply two coats of epoxy with proper flash times between coats and let it sit
over night before painting.
Remember, reducing epoxy speeds up the cure time, so when mixed as a sealer the best
application of base is within 2-18 hours (no sanding is needed within this time frame).
1:1:1 is 50% reduction which has always worked well for me.

Thanks coronet, (sorry I misspelled your name earlier) coronet reminds of a neighbor we had 30 some years ago, he had a coronet wagon, but anyways jumping (fast forward) in a couple weeks, I'm looking to do my first overall and Barry suggested I use euro clear, (I'm guessing) two gallons +activator +reducer will be enough for my truck and a couple practice runs on a spare tailgate?
The induction time makes this more complicated. If it wasn't for induction, you mix up a full cup, spray until you run out, then mix up some more to continue. I would estimate about 40 oz of rts, much different than coronet's estimate, so not sure what you want to do with that. How large is your spray cup? I use an LPH400, 1.4 tip, and 22 psi.
