Well Geoff your a brave man, trying a Trabi. I've seen quiet a few around Europe and even further afield, but none of them had glossy paint! I was going to buy one of these estate car kits and turn it into a touring car racer, with BBS rims race seat and a roll cage, but of course if it did roll over the cage would be OK but the body would disintegrate!
It reminds me of the old Reliant Robins!
On my way to work one morning, there was a strong side wind on the road. I was just about to go over a railway bridge where there was the brick parapets on each side of the road. All I could see was a pile of fibreglass and further on the bare chassis of the Robin with only the seats, engine and gearbox. Of course he had kept the steering over to keep it in a straight line against the wind and coming across the brick wall it swerved across the road and smashed itself to bits!
Sorry I'm getting of the point, good luck with the kit, but the paint seems to be of some concern.
