Have to agree.
Add it up:
Typical factory DFT = 120μm
Epoxy (as sealer, non-sanding) = 30μm
Epoxy (2 coats, sanding) = 100μm
HS primer (2 wet coats) = 120μm
Basecoat (3 light, wet coats) = 45μm
Candy (3 coats, medium wet) = 90μm
Clear (3 coats, medium wet) = 90μm
That's 495μm using just a single sealing coat of epoxy or 565μm if 2 coats of epoxy. Either way it's well over 300μm which is the effective DFT limit for a job that will last. Understand that intent is to keep the car inside/covered but he wants to take it to shows and paint that is too thick will hurt his results. Extra coats of candy or clear will just make it worse.
You or I might be able to put coats down a bit lighter but still even, however someone inexperienced is much more likely to lay the coats much thicker and heavier.
If it was me, I'd block existing paint back as far as possible to get a level base before paint and then just a very thin sealing coat of epoxy, followed by just two coats of base, wet on wet with only two coats of candy and two coats of clear. Leave that all to cure for a week or two then maybe two more coats of clear as sacrificial layers to wet sand and buff.
As you know, two coats of candy means you have to get it down very evenly, again a risk for someone new.
