Pour boiling water over the joins [it kills the solvent] and gently ease the trim off.

If it won't come away easily, get a wallpaper scraper, wrap it in a cotton T-Shirt [so not to scratch your paint] and use it to prise your way along the trim, bit by bit

Have a tub of T-Cut ready after for any stubborn glue, or just to fade the paint back into the bodywork as it may have discoloured a bit, then remember to polish after
