removing foil backed graphics

[Guy]

mate has a builders van that he has picker up... but he wants to remove the graphics

the graphics are foil backed so proving a right pain and just disintegrating, took him about an hour and a half to do half of one of the big letters

he has tried warming them up to no effect and also soaking them with petrol

any suggestions please?

Heat it up get a plastic scraper and keep heating as you scrape..

or heat a cloth in boiling water for a while then hold it on the sticker and then do above..

its still gona be a long winded process
