OMG!!!!
Sorry to see such a disasterous result.
Hope you manage to get it sorted quickly and without too many problems, keep us up to date with how you get on.
I tried my kit out yesterday at Peterborough in similar weather to yours.
The excess paint after 10 minutes was quite difficult to remove, a fair amount of pressure and rubbing was required to remove it sucessfully.
The application of the paint and the removal of the excess is not as straightforward as the instructions would have you believe.
