Hi
I have never hand washed my car before but decided to give it a go since i am rarely happy with the results from a car wash. Very satisfying but a hard work, especially on a car which wasn't washed for months. Tree sap was super difficult but overall i am happy. I used Autoglym tar remover for tree sap, and then Autoglym Foaming car wash. The only thing is that after washing I noticed a weird white residue mostly on the roof and bonnet. It does not come off easily. Actually it does not come off at all. A while ago there was a large construction site next to my house and some neighbours complained that cement residue was settling on their cars. Can it be it? Any advice on how to get rid of it?
Some people suggested it may be a clear coat giving up.
My plan before I discovered it was to use Autoglym Super Reisin Polish applied by hand. I am not comfortable yet with using machines. Is it likely to work on these spots (I would check but SRP is still in the post).
Thank you
