Get some panelwipe or thinners, soak a rag in it and apply liberally to the glue, leave the rag spread out over the glue for at least a minute for thinners to soak in, then glue should come off alot easier
Definately go steady with the thinners, you'll need to T-cut after if you use that. Petrol or white spirit should be adequate. Dab the lot then use hard plastic; like a credit card to scrape the glue back. Good luck :ILU:
I ve always used petrol and plastic ice scrapper. if stubbon leave a rag socked in petrol on it while you have a coffee then scrape off, i have always found after that i have had to T Cut and polish after as it leaves a shadow on paint. T Cut will remove any slight traces of glue.
