Re-painting van floor

[Chefgage]

What would be the best paint to use on my MK7 inside floor. At present it's not too bad. I have a few bolt holes to fill (small holes, to be filled with isopon filler). But I would like to paint it before I continue with my campervan build. The existing white paint is in mainly in a good condition.
I have a tin of por15 top coat going spare but was wondering what the best options were?

The last van floor I painted was a mk 3 I had to plate two holes and use rust converter on the surface rust then used Hammerit when dry I waxoiled before putting the floor down.

Thanks for that. I will take a look at some hammerite

If you can put up with the smell on first application it does fade away waxoil or similar is really worth using on top of the paint.

Thanks again. I will give it a go. I know I am going to be covering the floor but I do like the idea of having it all nice and shiny white before I cover it up.
