fibreglass thickness

[toms-dad]

I have a project 1970 vixen that I am hoping to start this year.
I am considering doing the fibreglass prep myself and have started to give the shell a look over.
The fibreglass is considerably thinner than that of the 92 griffith that i have ( less than half).
Can anyone advise me of the standard fibreglass thickness of these shells.

Cheers.

Having looked at the bodywork, most of it appears to be about 1.5 mm (at the edges). Just a little suprised. should be able to lift it off with 1 little helper.
Took eight of us for the Griff.
