Hey mate, I've been browsing this site for a while and only just getting into posting ... but your car has always been one that I've enjoyed reading about. Good on you for getting stuck into the underside.

I thought I had some tips for you as at work I often deal with tight hardware (otfen smaller diameters) but mercury grey minter beat me to the punch. Man you gotta lube up.

Here's a snapshot of some of the gear I use.



WD40 is spot on ... CRC5.56 is a little better but ZEP45 is the tits! It has teflon (ultimate lube) particles in it and awesome penetrating abilities (even better if you can get to both sides of the bolt). Good luck finding it though ... its hard enough in AUS and costs $25AU. Spray them on but give them time to soak.

My advise is ... use good tools. Cheap tools will round the head off a loose bolt. Mercury grey is spot on if it is tight (with a proper fitting socket) tighten it up a little before you loosen it ... (or if it is a screw fit the tip in and smack it with your hammer) Ye old shock treatment works.

Good luck ... I look forward to seeing the results.
