Hi There!
Restoration some progress, but slow.... Diff neatly wrapped up. Cheapo cling-film, wonderful stuff to keep the muck and rust at bay
Anyway to answer your question
I have heard about seal reaction but I haven't suffered from that in the car I used it in. However I completely rebuilt the braking system and thus there weren't any traces of "normal" brake fluid in there
So the M6 has gone, shame I was tempted but Mrs Malc would have got REALLY upset if I came home with yet another car
You moved house yet?
