Hmmm

That is odd, I think you and Jim are probably bang on with the assumption
of the formation of hard molecules in the iron, leading to microcracking
by the sounds of it.

so opening up a whole new can of worms.....

Ceramic coatings seem like a better alternative all round then? Any
experience with them?

I am out of time for now so will be removing the wrap and putting
everything back togeather over the next 2 weeks (working audi for
Christmas present with any luck) as driving the Miata in the snow is fun
but a bit deadly really.

Cheers

Timmy
