Hi, not exactly a technical question! But bought an ex hire 06 daily luton, I do removals so it needs to look clean, the outside and cab are great, but inside the luton box is really marked, I cleaned it today with bleach and water but still alot of marks - to be expected on an 8 yr old hire van! Does anyone know whether I can spray the inside of the box (just the 2 plastic sides and luton overhead bit). Also I want to fit some new tie rails, wooden ones to tie strapping to, any help on this? thanks.
