Anyone know the thickness of the birmabright panels on series rovers in decimal, fraction, or gauge form?

Depends upon which Series. The SII (not A) panels are thicker than the IIA and it is possible the SIII is a tad thinner yet. I believe they switched to a cheaper aluminum alloy starting with Defenders, and the aftermarket panels seem to be made from light duty aluminum foil.

that explains so much!! thanks!!Originally Posted by ignotus
they say that many many manufacturer's made an exact same formula of alloy....but I
tend to disagree. My uncle used to be a managing engineer at AlCOA...and he says that while they did have an aluminum and magnesium (I fpget the alcoa #), it was the ratios between the three metals (aluminum, magnesium and manganese) that varied slightly between manufacturers...even though they weren't supposed to.
I think Birmabright Ltd(or whatever they were called officially) had just hit upon the perfect ratio of those three metals...maybe wth just enough manganese to counter all but very minimal oxidation.
