Expoxy Coverage Thumbrule

Hi, everyone. Getting close to doing my first painting ever, shooting the bottom of a Triumph Spitfire with epoxy. Still some prep to do, following the tech manual closely, but was curious about coverage. I don't want to mix too little paint and would rather not mix too much so as to minimize waste. Is there a thumb rule for how much paint to mix depending on how much I'm painting, sort of like there is for painting a bedroom or something? I'm going over bare metal.

Thanks so much,
Chris
 
8 oz mixed per panel per coat has seemed to be pretty accurate for me with fenders/doors/quarters. If you are doing the bottom of an entire car, I would say that is 2-3 panels worth.
 
Thanks, Mitch. I had found that recommendation on the forum here, but I wasn't really sure what constituted a "panel". It's a Spitfire, so my panels are about 1/2 (or less) the size of typical panels. The whole bottom of the floor is pretty flat and only about 9ft long by 4ft wide.

Thanks!
 
Here is what I have done for years and it has worked extremely well. Mix more than what you think youll need for first coat. Write down what's left and mix enough for second coat. For example, mix 20 ounces, if only used 8 oz youll have 12 oz left. Then mix 8-9 oz. Keep records of your mixes. Later if needed you'll know how many coats, etc. If doing 3-4 coats you may find that you don't need to mix as much. If waiting 30 minutes between coats of epoxy pouring leftover back into cup also allows time to run thinner thru spray gun to keep it operating at peak efficiency. Hope this helps.
 
It does, thanks, Elwood. It'll take some getting used to, but I think I've got a good idea. Appreciate it!
 
For clarification in the above example of mixing 20 oz, having 12 oz leftover, if only doing 2 coats no more mixing would be needed. I usually spray 3-4 coats so I always end up mixing more. I usually don't have more than 2-3 ounces left over after spraying. This really helps when trying to not run out of something.
