so most of the advice is to take the ply out & your still going to leave it in.
why did you ask

LOL - I think my choices were;
Remove the ply then paint and leave
Remove the ply then paint and replace the ply
Leave the ply and paint over it
Leave the ply and do nothing
Put a rubber mat or lino down
After all the helpful answers I was not 100% convinced that lifting the ply was necessary.
I briefly looked for a liner on ebay, and rang Peugeot parts to see if they had one - both drew a blank.
I therefore need to make a decision as I haven't got long before installation, and thought that the insulating/hardwearing properties of the ply, with an additional protective layer of paint was the best compromise for me, without the hassle of lifting the sealed ply and preparing the surface.
I asked because I wanted the opinions of those that have experience, and I'm grateful for the replies. I might still change my mind
