Hi all, bit of a boring non techical question! Just bought an 06 ex rental luton, bodywork and cab are in nice condition, but inside of luton box is quite marked as tie rails are only present high up in the van, so obviously stuff was hitting sides alot in its 8 year rental useage. I cleaned it earlier with water and bleach but still alot of marks. Can I spray it? (it is white obviously!), I just thought I'd spray the 2 box sides and luton overhead bit (inside), to make it look clean ( I run a small removal company). Is this possible as its plastic, and I need something that won't rub off onto whatever I put in the van (furniture etc). Thanks.
