Jim! you inspired me to have a go and I have now RUINED them!!!
Dont worry they were all old corgi crap anyway.
1st was a london taxi cab, I filled off some of the paint and repainted and thought, yeah thats good and put it aside (but not far enough)
The next car was a Lotus espri (dont know how to spell
) and filled the paint off that and then tried to repaint, and it wasn't going to have any off it none of the paint was sticking so, oh well. Then I noticed my taxi cab, all the fillings from hte lotus where now all stuck to the paint
The final wasn'tvery bad at all
A mercades minibus thing (like the one you did) and tried converting it into a van, I accidentally completely destroyed the chassis while trying to get it off but good news!1 the plasticard strips are sticking very well to the side. and thats all I've done to it
