Bird droppings

[Tonyash]

Trying to be polite here by referring to the problem as bird droppings .......
Where I park my Berlingo on my drive is beneath an ornamental tree which is on next doors property. At this time of year pigeons are attracted to the blossom. Daily I clean the roof, bonnet or anywhere which is splattered by these pigeons.
Does anyone know of a product - polish, sealant or other which would prevent the paintwork being damaged by this nuisance, it's not really practical to have a cover which would be removed and replaced daily.
Thanks
