My paint instructions make no sense to me. What are “2K UP Products”. They apparently have different rules for using it as a top coat filler.

I assume you know that 2k means that it is base + catalyst. I am guessing that UP means ultraviolet protection, meaning it is ok to use as a topcoat. As an example the Southern Polyurethanes 2K epoxy is a great product, but they don't (or at least didn't used to) recommend it as a top coat or final finish, because of UV exposure.

Oh yes, the 2K, I wanted to put some context to the “UP”.

The difference is with “UP products” there is a strict 12H flash time vs 30 min for traditional fillers. Im like WTH is UP products

Bring back the Dupont Dulux paint or even Centari. Today's auto paint materials are absurd.

I went ahead and just painted it...sanded it today...yup burned through some areas just like I thought I would....WTH! Now I have to sand these areas with a coarser grit just to lay more epoxy rather than the filler primer getting me closer to paint!

You can still get Duponts stuff from a Axalta dealer. They still use same part numbers in most cases.
Axalta Bought out Duponts refinishing stuff.

That is correct, although it's well past the "legal" timeline to sell any paint products that has the "DuPont Oval" on it's label, but it would be considered outdated stock anyway.

Actually, the Axalta name came about only after DuPont sold it to the private - equity firm called The Carlyle Group, then it was renamed and branded with a new name, Axalta.

And, as private equity firms go, they do what they are good at, and they did well at that.

What grit are you sanding with?
If you've missed the recoat window it should only need a scotchbrite scuff for the next coat or 180G for polyester filler (bondo)
