tea tree oil? has always worked for me, thou the stuff you are dealing with sounds pretty stubborn

White Spirits, one of the most underrated cleaners, great for sticker residue and heaps of other things.
Won't affect your paint.

I tried toluene (sp?) for removing some residue and it worked well. I bought it from Bunnings, in the paint section.

I think its also meant to be a paint solvent, so try with care. Supposedly a carcinogen too, and good octane improver.

Pure turpentine seems to do the job without removing the paint.
And I don't mean the usual mineral turps, for paint thinners.
Pure turps is a natural distilate from wood I think and completely different to mineral turps.

I've used pure turps many times to remove old stickers from sails and things and it seems to do so without wrecking the sail.
It takes about 5 minutes to soften the glue and then you can just roll it off with a cloth. It's a messy procedure.
Try it on a small section first.

From experience, all cleaners above might work but the residue will have affected the finish on the van. The only way to remove all remnants of surface damage is with a good cut and polish.

Have you seen his van plus cut and polish will not remove glue

[EDIT]

I read this as sticky residue in van so my previous suggestion is no longer needed

You are such a grubby man!

Should have left the flames on it....

This gear is available from Bunnings - www.de-solv-it.com/

It works well on boards and is even safe on sails to remove sticker goop. Worth a shot, not too expensive and readily available

Just let me know where I can get a can of 'Mother-in-Law Off'
