Yes I agree with all on here with autoglym the rapid wax can only be used when the paintwork is wet as I use with the final rinse and then spray on and towel . Afterwards I use atoglym super rasin polish then wax . You can buy bird wipes from autoglym

But as you say a little water on the area and use the rapid wax . Have to watch out for seeds in the poo as they can scratch really bad so wet down as must as you can so not to mark the paint work .
I can say I have used autoglym for 30 odd years now and have never had a problem with bird poo .
One thing I will share ( sun cream lotion ) now that does mark the paint work as years ago my oldest son put his hand on our car and it stayed on the car for years . As it almost burns the paint to a white mark .
Andrew that’s a good price for the wax amazon it’s over £40 I think . Nice find mate .
