Angry Help! Paint/Primer won't stick to cabinets

We bought a second hand kitchen off trademe (NZ's equivalent to ebay) and want to paint the cabinets. They're currently finished with a 2 pot. I asked at the trade store and the paint man told me that I didn't need another 2 pot, as sanding, priming and using a semi-gloss (I bought the premium kind - Resene) would work just fine. Well, I sanded the entire oven fascia with an electric sander and 120 grit, then hand sanded it. Wiped away the residue and waited a day. Painted oil-based multi-purpose sealer/primer/stain block onto it and then once that was dry, I painted 2 coats of the semi-gloss. It scratches off!!!!!
My partner tried an etch primer on a separate piece of cabinetry (same finish) and that primer scratches off too!!!!
What can I do?!?!?! please help!!!!

Welcome to the forums!
They're currently finished with a 2 pot.
Can you further explain this? I don't know what that means.
Is this a stove with a porcelain type finish on it? If so, it's not really a suitable substrate for paint.

Guessing this is an oven cabinet?

Resene paints appear to be in Australia but regardless something is not adding up, are we talking wood cabinets??

As noted not familiar with the term 2 Pot but maybe some type of 2 part epoxy which might explain why nothing is sticking!

If it's a 2 part epoxy, it can still be painted over but a lot depends on the type of epoxy and the type of paint being applied over it.
I hope it wasn't a latex paint being applied over the epoxy! While they can take a week or more to fully cure, latex won't ever bond well to epoxy.

Yes, it's an oven cabinet, so it's MDF. I think it's 2 part epoxy? To my knowledge they were spray finished by the joiner who made them, so not 100% sure what they're done with. The paint I'm using over it is called Lustacryl, which is a semi-gloss waterborne enamel.

How long did you allow the primer to dry before applying the finish paint? Does the paint scratch off all the way down to the original finish? Did you wipe off the sanding dust prior to applying the primer?
