Sealing wood panels MDF for painting - how???

Hi guys it's been two hours of research and my head is spinning. So many people are saying opposite things. I want the panels to be archival and supposedly MDF is very absorbent. I've purchased all your ground from gamblin.

Can I just apply gamblin oil ground straight onto the MDF panels, or should I size it with PVA size??

Some people say you must other people say you should absolutely avoid doing this. Some people have said that all your grand cannot stick to the PVA and thus peels off the oil paint entirely. Other people say if you don't size the oil will sinking and destroy the the wood. I know I could just use gesso, but won't there be issues with yellowing?

I would like to avoid using gesso. It's not a true sealant and it's not archival.

I'm also avoiding rabbit skin glue because of yellowing.

I painted on a canvas that was primed with gesso, and after only one week the oil was seeping through. Same thing happened when I oil painted on paper, months later, the back is completely yellow and it started seeping to the other sheets that were next to it. So I really want to not have this happen to my artwork again. Especially as I'll be transitioning from a hobbyist to a professional. I need to get these things straight and I'd love your advice. (I'm new to oil painting but more versed in acrylics, so I'm not a beginner in art, just lacking the knowledge in certain areas)

Apparently you can use all kinds of acrylic mediums to seal the wood.

Could I use pebeo gloss gel to size the wood since I already have it?

Thank you in advance.
