I had never heard of anti fish eye/ anti silicone - thanks for telling me.
I've been out and bought some already.
I might get time tomorrow to sand it again and next time that dry weather coincides with my garage time I will be redoing it with the anti silicone, and definitely not using the hot air gun
Some good news, I phoned Newham council, explained what had happened, apparently they have a whole department dedicated to hot rodders who have had paint issues whilst paying for their other car to be parked on the road, they are going to refund my £1.67.
Or maybe I should've saved that tale for April 1st?
EDIT so with the wings needing to dry I jumped onto the brakes. The system was completed a week or 2 ago, so this afternoon I checked every join, then bled the system. All working now, I even jacked up one corner and turned the wheel by hand to prove that the brakes work!!
