Well I got no pics sry, but I will try to explain it:
First u need the lexan and a hot air gun(not one for your hairs ).
Then you should start like this:
1) Screw the lexan on your chassi. I use the two screws at the front and the two screws which hold the gearbox and the the srew which hold the shocktower.
2) then start heating the foil but be careful and dont stop moving, because if you stay too long on one place the lexan will be white and loose his flexibility. So you can pull the foil over the chassi ang give them the shape.
Good Luck
