Tim, that really is sounding better and better. It's nowhere near Clarkson's quip that he repeated numerous times on Top Gear when he drove a Hawk Stratos ..... 'built by a bloke with a hammer in a shed in Birmingham'.
I'm sure you will get a huge amount of fun out of it, both in the recommissioning and in its use.
With regard to 'tyre softener' I would have a word with James (aka Chugga Boom) at Minera tyres, he has the expert knowledge. 01978 757052.
