yeah dead easy to remove, just heat it up till it bubbles with a decent heat gun (i have a bosch one, excellent bit ogf kit ) then scrape it off with a wall paper scraper.
it will leave a residue of glue there, that can be removed with petrol or proper oil/tar remover.
as for replacing it, think you can buy the stuff as rolls, i know bodyshops use it so maybe local one can get some for you?
