Has anyone got a recommendation for a tarpaulin type cover to protect Citroen relay 2018 windscreen from leaves and birds mess at this time of year? Looked on Amazon and ebay...well crawled through them! Seems to be many which advertise as for vans but would be too small and not cover the gutter bit. Also some have magnets (scratch bodywork) and some have elastic. Any personal pointers would be appreciated!
