Hi Jimmy
I am using 1.2mm half hard for the bodywork & used 2mm for the floor n fuel tank.
The rear panel formed a lot easier than I expected & was no trouble at all to make
The floor is well sorted, without the slightest hint of a boing when stepped on .... Probably due the the gazillion rivets used
Not saying 1mm is wrong .... Just a tad lightweight for my own personal taste.
That is a very good price on the 1.2mm alloy, talk about the " luck of the Irish "
