Okay we had a day of rain that delayed things but when I went down to the car, oh dear. See those big green trees in the background? The reason they look so bright green is because the leaves are just coming out and dropping the bud husks all over my car as you can see on the bonnet
The garage seems to be blocking anything coming in from behind and the sides are holding up well. As the wind is blowing from the garage towards the from of the car I might get away without needing to make any more plastic walls.
I have wiped the back of the car clean and will see what it looks like in 30 minutes. If it is still clean then we are good to paint.
