Mine is ply lined and varnished at the mo
Thinking of ripping it out and applying a water proofing type paint supllied free from a massive waterproofing / sealants company where the missus works...
I let you know how that works and maybe be able to get a job lot cheap if anyone interested
Think the leaks n drips have worked under the floor ply so want to sort that out
plus i have noticed i have condensation problem to roof in the rear of the van

any ideas or is this common ( i suspect not)
Thanks
Paul
